Subject: [PATCH v2 2/2] drivers: net: ethernet: 3com: fix return value
Date: Sat, 24 Dec 2016 13:02:38 +0100 [thread overview]
Message-ID: <1482580958-15406-3-git-send-email-thomas.preisner+linux@fau.de> (raw)
In-Reply-To: <1482580958-15406-1-git-send-email-thomas.preisner+linux@fau.de>
In some cases the return value of a failing function is not being used
and the function typhoon_init_one() returns another negative error
code instead.
