Subject: [PATCH] notifier: Simplify expression
Date: Thu,  5 Jan 2017 10:42:32 +0530
Message-ID: <> (raw)

NOTIFY_STOP_MASK (0x8000) has only one bit set and there is no need to
compare output of "ret & NOTIFY_STOP_MASK" to NOTIFY_STOP_MASK. We just
need to make sure the output is non-zero, that's it.
