  • 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

  • 79289e241   ALSA: usb-audio: Refer to chip->usb_id for quirks and MIDI creation ... Browse Code »

    This is a preliminary patch for the later change to allow a better
    quirk ID management. In the current USB-audio code, there are a few
    places looking at usb_device idVendor and idProduct fields directly
    even though we have already a static member in snd_usb_audio.usb_id.
    This patch modifies such codes to refer to the latter field.

    For achieving this, two slightly intensive changes have been done:
    - The snd_usb_audio object is set/reset via dev_getdrv() for the given
    USB device; it's needed for minimizing the changes for some existing
    quirks that take only usb_device object.

    - __snd_usbmidi_create() is introduced to receive the pre-given usb_id
    argument. The exported snd_usbmidi_create() is unchanged by calling
    this new function internally.

    Clean up the usb audio driver by factoring out a lot of functions to
    separate files. Code for procfs, quirks, urbs, format parsers etc all
    got a new home now.

    Moved almost all special quirk handling to quirks.c and introduced new
    generic functions to handle them, so the exceptions do not pollute the
    whole driver.

    Renamed usbaudio.c to card.c because this is what it actually does now.
    Renamed usbmidi.c to midi.c for namespace clarity.
    Removed more things from usbaudio.h.

    The non-standard drivers were adopted accordingly.
