Subject: [PATCH v4 2/2] net: 3com: typhoon: typhoon_init_one: make return values more specific
Date: Fri, 30 Dec 2016 03:37:54 +0100	[thread overview]
Message-ID: <1483065474-11512-3-git-send-email-thomas.preisner+linux@fau.de> (raw)
In-Reply-To: <1483065474-11512-1-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.
