Subject: audit: make audit_log_common_recv_msg() a void function
X-Git-Tag: firefly_0821_release~176^2~785^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=233a68667cf4c134d07ef7e22bdd77786b5c7360;p=firefly-linux-kernel-4.4.55.git

audit: make audit_log_common_recv_msg() a void function

It always returns zero and no one is checking the return value.
