Subject: rtc: rtc-sh: switch to using SIMPLE_DEV_PM_OPS
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0ed5054447462976b7577ccf08d422c93ea38095;p=openwrt%2Fstaging%2Fblogic.git

rtc: rtc-sh: switch to using SIMPLE_DEV_PM_OPS

Switch to using the SIMPLE_DEV_PM_OPS macro to declare the driver's
pm_ops.  It reduces code size.  Also, CONFIG_PM_SLEEP is added to prevent
build warning when CONFIG_PM_SLEEP is not selected.
