The patch titled Subject: drivers/rtc/rtc-ds1305.c: use devm_* APIs has been removed from the -mm tree. Its filename was drivers-rtc-rtc-ds1305c-use-devm_-apis.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Sachin Kamat <sachin.kamat@xxxxxxxxxx> Subject: drivers/rtc/rtc-ds1305.c: use devm_* APIs devm_* functions are device managed and make cleanup code simpler.
