From 5fb437984b6c4793626be3936297fecece987a9f Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Mon, 23 Nov 2015 17:24:32 +0530 Subject: [PATCH] misc: mic: use common error path Instead of calling release_firmware() on every error and then jumping lets have a common release_firmware() in the error path. This patch also fixes a memory leak where we missed release_firmware() if mic_x100_load_command_line() fails.
