From 3e6daded1f51b79ff851b6c1e4b192f47ea3d063 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 24 Feb 2017 15:00:44 -0800 Subject: kernel/notifier.c: simplify expression 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.
