Subject: [PATCH net] cxgb4: Signedness bug in init_one()
Date: Wed, 25 Sep 2019 13:54:59 +0300 [thread overview]
Message-ID: <20190925105459.GB3264@mwanda> (raw)
The "chip" variable is an enum, and it's treated as unsigned int by GCC
in this context so the error handling isn't triggered.
Fixes: e8d452923ae6 ("cxgb4: clean up init_one")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
