Subject: [PATCH] ASoC: fsl_aud2htx: mark PM functions as __maybe_unused
When CONFIG_PM is disabled, we get a warning for unused functions:
sound/soc/fsl/fsl_aud2htx.c:261:12: error: unused function 'fsl_aud2htx_runtime_suspend' [-Werror,-Wunused-function]
static int fsl_aud2htx_runtime_suspend(struct device *dev)
sound/soc/fsl/fsl_aud2htx.c:271:12: error: unused function 'fsl_aud2htx_runtime_resume' [-Werror,-Wunused-function]
static int fsl_aud2htx_runtime_resume(struct device *dev)
Mark these as __maybe_unused to avoid the warning without adding
an #ifdef.
Fixes: 8a24c834c053 ("ASoC: fsl_aud2htx: Add aud2htx module driver")
