From a844b43ca078d7dd8f0cd13c6f030ec62a996975 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 22 Mar 2011 16:34:01 -0700 Subject: [PATCH] drivers/misc/atmel_tclib.c: fix a memory leak 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.
