From: Christian Engelmayer Date: Wed, 7 May 2014 19:44:53 +0000 (+0200) Subject: staging: binder: fix usage of uninit scalar in binder_transaction() X-Git-Tag: v4.14-rc1~7083^2~39^2~533 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7d42043f093ed83ef80f03b17087a1eaaf8d2e06;p=platform%2Fkernel%2Flinux-rpi.git 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.
