From 19318de1daf25aa1ca4fe76e1d7ac834f1bfb0c4 Mon Sep 17 00:00:00 2001 From: Christian Engelmayer Date: Sun, 18 May 2014 16:00:40 -0700 Subject: [PATCH] Input: ims-pcu - fix uninitialized use of 'error' in ims_pcu_buffers_alloc() In case allocation via usb_alloc_coherent() fails in ims_pcu_buffers_alloc(), the function jumps to the exit path without initializing local variable 'error' that is used as return value.
