Date: Mon, 22 Nov 2010 16:44:27 +0800 From: Axel Lin <axel.lin@...il.com> To: linux-kernel <linux-kernel@...r.kernel.org> Cc: Chris Ball <cjb@...top.org>, Andrew Morton <akpm@...ux-foundation.org>, Vipin Bhandari <vipin.bhandari@...com>, David Brownell <dbrownell@...rs.sourceforge.net>, linux-mmc@...r.kernel.org Subject: [PATCH 1/4] [ARM] davinci_mmc: 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.
