Subject: [PATCH] cw1200: Fix a signedness bug in cw1200_load_firmware()
Date: Wed, 25 Sep 2019 10:59:43 +0000 [thread overview]
Message-ID: <20190925105943.GJ3264@mwanda> (raw)
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")
