[PATCH AUTOSEL for 4.9 13/56] net: 3com: typhoon: typhoon_init_one: make return values more specific

[alexander.levin@verizon.com]

From: Thomas Preisner <thomas.preisner+linux@fau.de>

[ Upstream commit 6b6bbb5922a4b1d4b58125a572da91010295fba3 ]

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.
