The patch titled drivers/rtc/rtc-omap.c: fix a memory leak has been removed from the -mm tree. Its filename was drivers-rtc-rtc-omapc-fix-a-memory-leak.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/ ------------------------------------------------------ Subject: drivers/rtc/rtc-omap.c: fix a memory leak From: Axel Lin <axel.lin@xxxxxxxxx> request_mem_region() will call kzalloc to allocate memory for struct resource. release_resource() unregisters the resource but does not free the allocated memory, thus use release_mem_region() instead to fix the memory leak. Also add a missing iounmap() in omap_rtc_remove().
