Message-Id: <1347858583-13338-1-git-send-email-sachin.kamat@linaro.org> Date: Mon, 17 Sep 2012 10:39:43 +0530 From: Sachin Kamat <sachin.kamat@...aro.org> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, sachin.kamat@...aro.org, patches@...aro.org, Arnd Bergmann <arnd@...db.de>, Marek Szyprowski <m.szyprowski@...sung.com> Subject: [PATCH] ARM: dma-mapping: Fix potential memory leak in atomic_pool_init() When either of __alloc_from_contiguous or __alloc_remap_buffer fails to provide a valid pointer, allocated memory is freed up and an error is returned. 'pages' was however not freed before returning error.
