Subject: block: fix improper kobject release in blk_integrity_unregister
X-Git-Tag: firefly_0821_release~13254^2~2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3839e4b29b4385e4b31075e7805683e2aa2a8103;p=firefly-linux-kernel-4.4.55.git

block: fix improper kobject release in blk_integrity_unregister

blk_integrity_unregister should use kobject_put to release the kobject,
otherwise after bi is freed, memory of bi->kobj->name is leaked.
