Subject: net: 3com: typhoon: typhoon_init_one: fix incorrect return values
From: Thomas Preisner <thomas.preisner+linux@xxxxxx>
[ Upstream commit 107fded7bf616ad6f46823d98b8ed6405d7adf2d ]
In a few cases the err-variable is not set to a negative error code if a
function call in typhoon_init_one() fails and thus 0 is returned
instead.
It may be better to set err to the appropriate negative error
code before returning.
