  • 498aaa915   ALSA: isa: 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!

    argument of snd_sb_csp_autoload() with the proper snd_pcm_format_t
    type.

    The PCM format type in snd_pcm_format_t can't be treated as integer
    implicitly since it's with __bitwise. We have already a helper
    function to get the bit index of the given type, and use it in each
    place instead.

    Pull media updates from Mauro Carvalho Chehab:

    - remove of atomisp driver from staging, as nobody would have time to
    dedicate huge efforts to fix all the problems there. Also, we have a
    feeling that the driver may not even run the way it is.

    - move Zoran driver to staging, in order to be either fixed to use VB2
    and the proper media kAPIs or to be removed

    - remove videobuf-dvb driver, with is unused for a while

    - some V4L2 documentation fixes/improvements

    - new sensor drivers: imx258 and ov7251

    - a new driver was added to allow using I2C transparent drivers

    - several improvements at the ddbridge driver

    - several improvements at the ISDB pt1 driver, making it more coherent
    with the DVB framework

    - added a new platform driver for MIPI CSI-2 RX: cadence

    - now, all media drivers can be compiled on x86 with COMPILE_TEST

    - almost all media drivers now build on non-x86 architectures with
    COMPILE_TEST

    - lots of other random stuff: cleanups, support for new board models,
    bug fixes, etc

  • da112f139   media: sound, isapnp: allow building more drivers with COMPILE_TEST ... Browse Code »

    Drivers that depend on ISAPNP currently can't be built with
    COMPILE_TEST. However, looking at isapnp.h, there are already
    stubs there to allow drivers to include it even when isa
    PNP is not supported.

    So, remove such dependencies when COMPILE_TEST.

  • e39fbc26a   media: sound, media: allow building ISA drivers it with COMPILE_TEST ... Browse Code »

    All sound drivers that don't depend on PNP can be safelly
    build with COMPILE_TEST, as ISA provides function stubs to
    be used for such purposes.

    As a side effect, with this change, the radio-miropcm20
    can now be built outside i386 with COMPILE_TEST.

    It should be noticed that ISAPNP currently depends on ISA.
    So, on drivers that depend on it, we need to add an
    explicit dependency on ISA, at least until another patch
    removes it.

    …e/sound into for-linus

    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

  • 20e5f8bfb   ALSA: sb: Minor optimization / fix of timer usage in sb8_midi.c ... Browse Code »

    Currently the SB8 MIDI code sets up the timer object at each time
    before scheduling it at trigger callback, but basically this is
    superfluous once after set up. Also, the code misses the
    del_timer_sync() call that may leave a race condition for
    use-after-free.

    This patch addresses these issues, moving timer_setup() to
    snd_sb8dsp_midi(), and adding the del_timer_sync() call at
    snd_sb8dsp_midi_output_trigger() to make sure.
