Subject: md: raid0: Fix a memory leak when stopping a raid0 array.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fb5ab4b5d6e16fd5006c9f800d0116f3547cb760;p=linux-beck.git

md: raid0: Fix a memory leak when stopping a raid0 array.

raid0_stop() removes all references to the raid0 configuration but
misses to free the ->devlist buffer.

This patch closes this leak, removes a pointless initialization and
fixes a coding style issue in raid0_stop().
