[PATCH 7/9] ASoC: SOF: Intel: hda-dai: mark functions as __maybe_unused

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hda_dai_hw_params, hda_dai_trigger(), hda_dai_hw_free are currently
only used for HDaudio codec support, but will be reused for
SSP/DMIC/SoundWire in the LunarLake/ACE2.x case. To avoid 'defined but
not used' errors or added complexity in Kconfig, mark all these
functions as __maybe_used.

When SSP/DMIC/SoundWire are added, some of these changes may be
reverted. For now this avoids compilation warnings.
