From 51d2eeef1d958ef6834b24f548194f5acea0f499 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Tue, 1 Sep 2015 11:14:05 +0530 Subject: [PATCH] ASoC: wm0010: fix memory leak We were aborting if the kzalloc of img_swap fails but without freeing the already allocated out. Similarly we were aborting if spi_sync fails without releasing out and img_swap.
