The patch titled Subject: drivers/rtc/rtc-twl.c: enable RTC irrespective of its prior state has been removed from the -mm tree. Its filename was drivers-rtc-rtc-twlc-enable-rtc-irrespective-of-its-prior-state.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Venu Byravarasu <vbyravarasu@xxxxxxxxxx> Subject: drivers/rtc/rtc-twl.c: enable RTC irrespective of its prior state As part of probe, before enabling RTC, RTC_CTRL register is read to check if it is already running. If RTC is used by kernel alone, then this read is not required. Even if RTC was enabled already by boot loader, setting STOP_RTC bit again should not harm. Hence removed unwanted read operation.
