      ASoC: imx-sgtl5000: Fix uninitialized pointer use in error path · 50d4a790
      Philipp Zabel authored
      This patch avoids to dereference the uninitialized data pointer if the
      error path is entered before devm_kzalloc is called (or if the allocation
      fails). It fixes the following warning:
      
          sound/soc/fsl/imx-sgtl5000.c: In function 'imx_sgtl5000_probe':
          sound/soc/fsl/imx-sgtl5000.c:175:18: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized]

      ASoC: imx-sgtl5000: do not use devres on a foreign device · a8b22c1c
      Philipp Zabel authored
      Calling devm_clk_get with any device pointer other than our own confuses
      devres. Use clk_get instead. This avoids hitting the following warning in
      the imx-sgtl5000 error path:
      
      imx-sgtl5000 sound.12: snd_soc_register_card failed (-517)

      ALSA : hda - not use assigned converters for all unused pins · f82d7d16
      Mengdong Lin authored
      BIOS can mark a pin as "no physical connection" if the port is used by an
      integrated display which is not audio capable. And audio driver will overlook
      such pins.
      
      On Haswell, such a disconneted pin will keep muted and connected to the 1st
      converter by default. But if the 1st convertor is assigned to a connected pin
      for audio streaming. The muted disconnected pin can make the connected pin
      no sound output.
      
      So this patch avoids using assigned converters for all unused pins for Haswell,
      including the disconected pins.

      ALSA: compress: Make sure we trigger STOP before closing the stream. · b26d19e4
      Liam Girdwood authored
      Currently we assume that userspace will shut down the compressed stream
      correctly. However, if userspcae dies (e.g. cplay & ctrl-C) we dont
      stop the stream before freeing it.
      
      This now checks that the stream is stopped before freeing.

      Anatol Pomozov authored
      'samples' is 64bit operant, but do_div() second parameter is 32.
      do_div silently truncates high 32 bits and calculated result
      is invalid.
      
      In case if low 32bit of 'samples' are zeros then do_div() produces
      kernel crash.
