  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • f6af5df0c   ALSA: aoa-soundbus: Switch to dev_pm_ops ... Browse Code »

    Update the aoa-soundbus framework to use dev_pm_ops rather than the
    deprecated legacy suspend and resume callbacks.

    Since there isn't anything special to do at the bus level the bus driver
    does not have to implement any callbacks. The device driver core will
    automatically pick up and execute the device's PM ops.

    As there is only a single aoa-soundbus driver implementing suspend and
    resume, update both the core and driver at the same time to avoid
    unnecessary code churn.

  • ef46c7af9   ALSA: pcm: Embed struct device ... Browse Code »

    Like previous patches, at this time we embed the struct device into
    PCM object. However, this needs a bit more caution: struct snd_pcm
    doesn't own one device but two, for both playback and capture! Thus
    not struct snd_pcm but struct snd_pcm_str object contains the device.

    Along with this change, pcm->dev field is dropped for avoiding
    confusion. It was meant to point to a non-standard parent. But,
    since now we can touch each struct device directly, we can manipulate
    the parent field easily there, too.

  • c2cdf6aba   powerpc/macio: Fix probing of macio devices by using the right of match table ... Browse Code »

    Grant patches added an of mach table to struct device_driver. However,
    while he changed the macio device code to use that, he left the match
    table pointer in struct macio_driver and didn't update drivers to use
    the "new" one, thus breaking the probing.

    This completes the change by moving all drivers to setup the "new"
    one, removing all traces of the old one, and while at it (since it
    changes the exact same locations), I also remove two other duplicates
    from struct driver which are the name and owner fields.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • ae31c1fbd   sound: remove driver_data direct access of struct device ... Browse Code »

    In the near future, the driver core is going to not allow direct access
    to the driver_data pointer in struct device. Instead, the functions
    dev_get_drvdata() and dev_set_drvdata() should be used. These functions
    have been around since the beginning, so are backwards compatible with
    all older kernel versions.

    This patch changes snd-aoa to handle some older machines that are
    currently handled by snd-powermac. snd-aoa has a number of advantages
    though, notably it can autoload better and is generally a more modern
    driver.

    By hardcoding the accepted device-ids (last hunk of the patch) I'm
    trying to avoid regressions because this driver will otherwise load
    automatically and not let snd-powermac load. People who are unhappy
    with snd-powermac and have a device-id property in the device tree
    are encouraged to read this patch and make a patch to amend this as
    appropriate.

    This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

    This changes the uevent buffer functions to use a struct instead of a
    long list of parameters. It does no longer require the caller to do the
    proper buffer termination and size accounting, which is currently wrong
    in some places. It fixes a known bug where parts of the uevent
    environment are overwritten because of wrong index calculations.

    Many thanks to Mathieu Desnoyers for finding bugs and improving the
    error handling.
