Subject: [PATCH] MFD: ucb1x00-core: add CONFIG_PM_SLEEP to suspend/resume
Date: Fri, 02 Aug 2013 14:45:25 +0900	[thread overview]
Message-ID: <000501ce8f43$7cc948b0$765bda10$@samsung.com> (raw)

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the build
warnings when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SET_SYSTEM_SLEEP_PM_OPS are only used
when the CONFIG_PM_SLEEP is enabled.

drivers/mfd/ucb1x00-core.c:672:12: warning: 'ucb1x00_suspend' defined but not used [-Wunused-function]
drivers/mfd/ucb1x00-core.c:704:12: warning: 'ucb1x00_resume' defined but not used [-Wunused-function]
