From 7d42043f093ed83ef80f03b17087a1eaaf8d2e06 Mon Sep 17 00:00:00 2001 From: Christian Engelmayer Date: Wed, 7 May 2014 21:44:53 +0200 Subject: [PATCH] staging: binder: fix usage of uninit scalar in binder_transaction() Fix the error path when a cookie mismatch is detected. In that case the function jumps to the exit label without setting the uninitialized, local variable 'return_error'. Detected by Coverity - CID 201453.
