Subject: [PATCH] ASoC: cs35l33: mark PM functions as __maybe_unused
Date: Wed, 29 Jun 2016 16:33:17 +0200 [thread overview]
Message-ID: <20160629143416.45214-1-arnd@arndb.de> (raw)
The newly added cs35l33 driver produces a harmless warning when
CONFIG_PM is disabled:
sound/soc/codecs/cs35l33.c:908:12: error: 'cs35l33_runtime_suspend' defined but not used [-Werror=unused-function]
sound/soc/codecs/cs35l33.c:868:12: error: 'cs35l33_runtime_resume' defined but not used [-Werror=unused-function]
This adds __maybe_unused annotations to shut up the warning
regardless of the configuration.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
