X-Git-Tag: firefly_0821_release~3680^2~4222^2~63
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5a4730ba9517cf2793175991243436a24b1db18f;p=firefly-linux-kernel-4.4.55.git

evm: fix evm_inode_init_security return code

evm_inode_init_security() should return 0, when EVM is not enabled.
(Returning an error is a remnant of evm_inode_post_init_security.)
