  • 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

    This macro is useful to avoid link error on 32-bit systems.

    We have the same definition in two drivers, so move it to

    While we are here, refactor DIV_ROUND_UP_ULL() by using
    DIV_ROUND_DOWN_ULL().

    - Small cleanup of PCM core

    ASoC:

    - Continued work for componentization; still half-baked, but we're
    certainly progressing

    - Use of devres for jack detection GPIOs, rather as a cleanup

    - Jack detection support for Qualcomm MSM8916

    ASoC: Updates for v4.14

    This is quite a large release by volume of patches and diff, a lot of
    that is mechanical cleanup patches but it's great to also see a range of
    vendors actively working on adding new features and fixing issues in
    their drivers. Intel and Realtek have been especially active here.

    - Continued work towards moving everything to the component model from
    Morimoto-san.
    - Use of devres for jack detection GPIOs, eliminating some potential
    resource leaks.
    - Jack detection support for Qualcomm MSM8916.
    - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
    systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson
    WM8523.

  • 4ab6cf11e   ASoC: atmel-classd: remove aclk clock ... Browse Code »

    Since gclk (generated-clk) is now able to determine the rate of the
    audio_pll, there is no need for classd to have a direct phandle to the
    audio_pll while already having a phandle to gclk.

    Thus, remove all mentions to aclk in classd driver and update macros and
    variable names.
