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

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.
