Subject: [PATCH] mmc: sdio: Fix PM_SLEEP related build warnings
Date: Thu,  9 Aug 2012 08:56:53 +0200	[thread overview]
Message-ID: <1344495413-7164-1-git-send-email-thierry.reding@avionic-design.de> (raw)

Power management callbacks defined by SIMPLE_DEV_PM_OPS are only used if
the PM_SLEEP Kconfig symbol has been defined. If not, the compiler will
complain about them being unused.
