  • 3b23dc52d   ALSA: i2c: Remove empty init and exit ... Browse Code »

    For a sake of code simplification, remove the init and the exit
    entries that do nothing.

    Notes for readers: actually it's OK to remove *both* init and exit,
    but not OK to remove the exit entry. By removing only the exit while
    keeping init, the module becomes permanently loaded; i.e. you cannot
    unload it any longer!

    ASoC: Updates for v4.15

    The biggest thing this release has been the conversion of the AC98 bus
    to the driver model, that's been a long time coming so thanks to Robert
    Jarzmik for his dedication there. Due to there being some AC97 MFD
    there's a few fairly large changes in input and the MFD layer, mainly to
    the wm97xx driver.

    There's also some drivers/drm changes to support the new AMD Stoney
    platform, these are shared with the DRM subsystem and should be being
    merged via both.

    Within the subsystem the overwhelming bulk of the changes is in the
    Intel drivers which continue to need lots of cleanups and fixes, this
    release they've also gained support for their open source firmware.
    There's also some large changs in the core as Morimoto-san continues to
    mirror operations into the component level in preparation for conversion
    of drivers to that.

    - The AC97 bus has finally caught up with the driver model thanks to
    some dedicated and persistent work from Robert Jarzmik.
    - Continued work from Morimoto-san on moving us towards being able to
    use components for everything.
    - Lots of cleanups for the Intel platform code, including support for
    their open source audio firmware.
    - Support for scaling MCLK with sample rate in simple-card.
    - Support for AMD Stoney platform.

  • 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

    In preparation for unconditionally passing the struct timer_list
    pointer to all timer callbacks, switch to using the new timer_setup()
    and from_timer() to pass the timer pointer explicitly. These are all the
    "mechanical" changes remaining in the sound subsystem.

  • e12483e0f   ALSA: ak4114: Fix wrong register array size ... Browse Code »

    The size of the register cache array is actually 6 instead of 7,
    as it caches up to AK4114_REG_INT1_MASK. This resulted in unexpected
    access out of array range, although most of them aren't so serious
    (just reading one more byte on the stack at snd_ak4114_create()).

    Also, the check of cache size was wrongly done by checking with
    sizeof() instead of ARRAY_SIZE(). Fixed this together.

    (And yes, hardcoded numbers are bad, but I keep the coding style as is
    for making it clear what this patch actually does.)

    Spotted by coverity among several CIDs, e.g. 711621.

    Pull media updates from Mauro Carvalho Chehab:
    "The first part of the media updates for Kernel 3.7.

    This series contain:

    - A major tree renaming patch series: now, drivers are organized
    internally by their used bus, instead of by V4L2 and/or DVB API,
    providing a cleaner driver location for hybrid drivers that
    implement both APIs, and allowing to cleanup the Kconfig items and
    make them more intuitive for the end user;

    - Media Kernel developers are typically very lazy with their duties
    of keeping the MAINTAINERS entries for their drivers updated. As
    now the tree is more organized, we're doing an effort to add/update
    those entries for the drivers that aren't currently orphan;

    - Several DVB USB drivers got moved to a new DVB USB v2 core; the new
    core fixes several bugs (as the existing one that got bitroted).
    Now, suspend/resume finally started to work fine (at least with
    some devices - we should expect more work with regards to it);

    - added multistream support for DVB-T2, and unified the API for
    DVB-S2 and ISDB-S. Backward binary support is preserved;

    - as usual, a few new drivers, some V4L2 core improvements and lots
    of drivers improvements and fixes.

    There are some points to notice on this series:

    1) you should expect a trivial merge conflict on your tree, with the
    removal of Documentation/feature-removal-schedule.txt: this series
    would be adding two additional entries there. I opted to not
    rebase it due to this recent change;

    2) With regards to the PCTV 520e udev-related breakage, I opted to
    fix it in a way that the patches can be backported to 3.5 even
    without your firmware fix patch. This way, Greg doesn't need to
    rush backporting your patch (as there are still the firmware cache
    and firmware path customization issues to be addressed there).

    I'll send later a patch (likely after the end of the merge window)
    reverting the rest of the DRX-K async firmware request, fully
    restoring its original behaviour to allow media drivers to
    initialize everything serialized as before for 3.7 and upper.

    3) I'm planning to work on this weekend to test the DMABUF patches
    for V4L2. The patches are on my queue for several Kernel cycles,
    but, up to now, there is/was no way to test the series locally.

    I have some concerns about this particular changeset with regards
    to security issues, and with regards to the replacement of the old
    VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
    GPU drivers change. The Overlay API allows direct PCI2PCI
    transfers from a media capture card into the GPU framebuffer, but
    its API is crappy. Also, the only existing X11 driver that
    implements it requires a XV extension that is not available
    anymore on modern drivers. The DMABUF can do the same thing, but
    with it is promising to be a properly-designed API. If I can
    successfully test this series and be happy with it, I should be
    asking you to pull them next week."

  • 43829731d   workqueue: deprecate flush[_delayed]_work_sync() ... Browse Code »

    flush[_delayed]_work_sync() are now spurious. Mark them deprecated
    and convert all users to flush[_delayed]_work().

    If you're cc'd and wondering what's going on: Now all workqueues are
    non-reentrant and the regular flushes guarantee that the work item is
    not pending or running on any CPU on return, so there's no reason to
    use the sync flushes at all and they're going away.

    This patch doesn't make any functional difference.
