  • a7f7f6248   treewide: replace '---help---' in Kconfig files with 'help' ... Browse Code »

    Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

    A lot of places in the driver use onyx_read_register() without
    checking the return value, and it's been working OK for ~10 years
    or so, so probably never fails ... Rather than trying to check the
    return value everywhere, which would be relatively intrusive, at
    least make sure we don't use an uninitialized value.

    ASoC: Updates for v5.1

    Lots and lots of new drivers so far, a highlight being the MediaTek
    BTCVSD which is a driver for a Bluetooth radio chip - the first such
    driver we've had upstream. Hopefully we will soon also see a baseband
    with an upstream driver!

    - Support for only powering up channels that are actively being used.
    - Quite a few improvements to simplify the generic card drivers,
    especially the merge of the SCU cards into the main generic drivers.
    - Lots of fixes for probing on Intel systems, trying to rationalize
    things to look more standard from a framework point of view.
    - New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341,
    Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek
    BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum
    DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.

    Both calls to of_find_node_by_name() and of_get_next_child() return a

    in the while loop if we reached the error code path below, an

  • 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

  • ef24ba709   powerpc: Remove all usages of NO_IRQ ... Browse Code »

    NO_IRQ has been == 0 on powerpc for just over ten years (since commit
    0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change
    platforms to use it")). It's also 0 on most other arches.

    Although it's fairly harmless, every now and then it causes confusion
    when a driver is built on powerpc and another arch which doesn't define
    NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
    some of which are to work around that problem.

    So we'd like to remove it. This is fairly trivial in the arch code, we
    just convert:

    if (irq == NO_IRQ) to if (!irq)
    if (irq != NO_IRQ) to if (irq)
    irq = NO_IRQ; to irq = 0;
    return NO_IRQ; to return 0;

    And a few other odd cases as well.

    At least for now we keep the #define NO_IRQ, because there is driver
    code that uses NO_IRQ and the fixes to remove those will go via other
    trees.

    Note we also change some occurrences in PPC sound drivers, drivers/ps3,
    and drivers/macintosh.

  • 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.
