3.16.82-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 4a50d454502f1401171ff061a5424583f91266db upstream.
The "priv->hw_type" is an enum and in this context GCC will treat it
as an unsigned int so the error handling will never trigger.
Fixes: a910e4a94f69 ("cw1200: add driver for the ST-E CW1100 & CW1200 WLAN chipsets")

[bwh: Backported to 3.16: adjust filename]
