Subject: [PATCH net-next 02/11] net: dsa: mv88e6xxx: Fix unused variable warning by using variable
Date: Fri, 11 Nov 2016 03:53:34 +0100 [thread overview]
Message-ID: <1478832823-31471-3-git-send-email-andrew@lunn.ch> (raw)
In-Reply-To: <1478832823-31471-1-git-send-email-andrew@lunn.ch>
_mv88e6xxx_stats_wait() did not check the return value from
mv88e6xxx_g1_read(), so the compiler complained about set but unused
err.
