      ASoC: Clean up error handling in MPC5200 DMA setup · 33d7f778
      Julia Lawall authored
      Error handling code following a kzalloc should free the allocated data.
      Error handling code following an ioremap should iounmap the allocated data.
      
      The semantic match that finds the first problem is as follows:

      ASoC: au1x: PSC-AC97 bugfixes · cdc65fbe
      Manuel Lauss authored
      This patch fixes the following bugs:
      
      - only reprogram bitdepth if it has changed since last call to hw_params.
      - add locking inside ac97_read/write functions:
        When reprogramming sample depth, the ac97 unit has to be disabled,
        which should not be done in the middle of codec register accesses.
      
      - retry timed-out codec register accesses.
      
      - wait for status bits to set/clear when starting/stopping various
        functional blocks; very important after reenabling AC97 unit else
        sound may be distorted (e.g. high-pitch noise in 1kHz sine wave).
      
      - clear fifos before/after starting/stopping RX/TX.
      
      - longer timeouts waiting for PSC/AC97 ready after cold reset
        with certain codecs this can take ridiculous amounts of time.
      
      Run-tested on various Au1200 platforms with various codecs.
