Merge series "ASoC: Clean-up W=1 build warnings​ - part1" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

Both Lee Jones and I submitted separate series, this is the first part
of the merged result, which includes all previously reviewed patches
or suggested changes along with trivial ones for CONFIG_ACPI.

Lee Jones (2):
  ASoC: codecs: jz4770: Remove defined but never used variable
    'mic_boost_tlv'
  ASoC: ti: omap-mcbsp-st: Remove set, but unused variable 'w'

Pierre-Louis Bossart (11):
  ASoC: atmel: fix kernel-doc
  ASoC: samsung: spdif: fix kernel-doc
  ASoC: samsung: pcm: fix kernel-doc
  ASoC: tegra: tegra20_das: remove always-true comparison
  ASoC: uniphier: aio-core: fix kernel-doc
  ASoC: codecs: da7210: fix kernel-doc
  ASoC: codecs: da7219: fix 'defined but not used' warning
  ASoC: codecs: cros_ec_codec: fix 'defined but not used' warning
  ASoC: codecs: es8316: fix 'defined but not used' warning
  ASoC: codecs: max98390: fix 'defined but not used' warning
  ASoC: codecs: rt*: fix 'defined but not used' warning
