cw1200: Fix a signedness bug in cw1200_load_firmware()
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") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
