Subject: [PATCH] ASoC: fsl_aud2htx: mark PM functions as __maybe_unused
Date: Thu,  3 Dec 2020 23:28:47 +0100	[thread overview]
Message-ID: <20201203222900.1042578-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

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")
