      ASoC: topology: Disable use from userspace · 8c90503b
      Mark Brown authored
      Since the topology API is still in sufficient flux for changes to be
      identified disable the use of the userspace ABI by adding #error
      statements to the code, ensuring that nobody relies on the headers as
      currently defined.  It is expected that this change will be reverted for
      v4.3.

      ASoC: topology: Add Kconfig option for topology · 78b50f39
      Mark Brown authored
      Allow the topology code to be compiled out so that users who don't need
      topology don't need to havve the code compiled in, saving them some
      memory.
      
      Some more configuration could be added to remove some of the hooks into
      the core data structures but that is probably best done with some
      refactoring to use functions to do the updates of the data structures
      rather than ifdefing in the code as we'd need to do at the minute.

      ALSA: usb: handle descriptor with SYNC_NONE illegal value · 395ae54b
      Pierre-Louis Bossart authored
      The M-Audio Transit exposes an interface with a SYNC_NONE attribute.
      This is not a valid value according to the USB audio classspec. However
      there is a sync endpoint associated to this record. Changing the logic to
      try to use this sync endpoint allows for seamless transitions between
      altset 2 and altset 3. If any errors happen, the behavior remains the same.

      ALSA: usb: fix corrupted pointers due to interface setting change · 63018447
      Pierre-Louis Bossart authored
      When a transition occurs between alternate settings that do not use the
      same synchronization method, the substream pointers were not reset.
      This prevents audio from being played during the second transition.
      
      Identified and tested with M-Audio Transit device
      (0763:2006 Midiman M-Audio Transit)
      
      Details of the issue:
      
      First playback to adaptive endpoint:

      Playing WAVE '/home/plb/16_48.wav' : Signed 16 bit Little Endian,
      Rate 48000 Hz, Stereo

      second playback to adaptive endpoint: no audio and error on terminal:

      This last line shows that a sync endpoint is used when it shouldn't.
      The sync endpoint is no longer valid and the pointers are corrupted
