Date: Wed, 25 Sep 2019 13:59:11 +0300 From: Dan Carpenter <dan.carpenter@...cle.com> To: Radhey Shyam Pandey <radhey.shyam.pandey@...inx.com>, "Alvaro G. M" <alvaro.gamez@...ent.com> Cc: "David S. Miller" <davem@...emloft.net>, Michal Simek <michal.simek@...inx.com>, Russell King <linux@...linux.org.uk>, netdev@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [PATCH net] net: axienet: fix a signedness bug in probe The "lp->phy_mode" is an enum but in this context GCC treats it as an unsigned int so the error handling is never triggered.
