  • config SND_AOA_TOPAZ has been commented out since it was added five
    years ago with commit f3d9478b ("[...] add snd-aoa"). There's no
    indication why it's commented out. It might as well be removed.

  • The i2c core will clear the clientdata pointer automatically.
    We don't have to set the `data' field to NULL in remove() or
    if probe() failed anymore.

    Also remove a unneeded NULL checking for kfree.

  • The label outnodev is only used when kzalloc has not yet taken place or has
    failed, so there is no need for the call for kfree under this label.

    A simplified version of the semantic match that finds this problem is as
    follows: (http://coccinelle.lip6.fr/)

    //

    expression E1!=0,E2,E3,E4;

  • of_device is just an alias for platform_device, so remove it entirely. Also
    replace to_of_device() with to_platform_device() and update comment blocks.

    This patch was initially generated from the following semantic patch, and then
    edited by hand to pick up the bits that coccinelle didn't catch.

  • 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.

  • …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.

  • In struct device_node, the phandle is named 'linux_phandle' for PowerPC
    and MicroBlaze, and 'node' for SPARC. There is no good reason for the
    difference, it is just an artifact of the code diverging over a couple
    of years. This patch renames both to simply .phandle.

    Note: the .node also existed in PowerPC/MicroBlaze, but the only user
    seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't
    look like the assignment between .linux_phandle and .node is
    significantly different enough to warrant the separate code paths
    unless ibm,phandle properties actually appear in Apple device trees.

    I think it is safe to eliminate the old .node property and use
    phandle everywhere.

  • 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.

  • Some machines have a master amp GPIO that needs to be toggled to
    get sound output, in addition to speaker/headphone/line-out amps.
    This makes snd-aoa handle it, if present in the device tree, thus
    making snd-aoa be able to output sound on PowerMac3,6, which was
    previously handled by snd-powermac which also doesn't use the
    master amp GPIO.

  • 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.
