Subject: [PATCH] selinux: avtab_init() and cond_policydb_init() return void
Date: Thu, 05 Mar 2020 15:04:33 -0500 [thread overview]
Message-ID: <158343867316.158870.5386750405980710812.stgit@chester> (raw)
The avtab_init() and cond_policydb_init() functions always return
zero so mark them as returning void and update the callers not to
check for a return value.
Suggested-by: Ondrej Mosnacek <omosnace@redhat.com>
