Subject: iop-adma, mv_xor: fix mem leak on self-test setup failure
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=a09b09ae51ace43d28cd9bc1c8bb97986f2b55a6;p=linux-2.6-omap-h63xx.git

iop-adma, mv_xor: fix mem leak on self-test setup failure

iop_adma_zero_sum_self_test has the brackets in the wrong place for the
setup failure deallocation path.  This error was duplicated in
mv_xor_xor_self_test.
