X-Git-Tag: accepted/tizen/common/20141203.182822~2439^2~48
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=688ef20250c472e183f34709c4be12af6341f927;p=platform%2Fkernel%2Flinux-arm64.git

misc: bh1780gli: add CONFIG_PM_SLEEP to suspend/resume functions

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

drivers/misc/bh1780gli.c:200:12: warning: 'bh1780_suspend' defined but not used [-Wunused-function]
drivers/misc/bh1780gli.c:222:12: warning: 'bh1780_resume' defined but not used [-Wunused-function]
