Subject: [PATCH] net: axienet: fix a signedness bug in probe
Git-commit: 73e211e11be86715d66bd3c9d38b3c34b05fca9a
Patch-mainline: v5.4-rc1
References: git-fixes
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.
Fixes: ee06b1728b95 ("net: axienet: add support for standard phy-mode binding")
