From c44cefceb3add724c135a4f57209ce66af5d40c9 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sat, 12 Jun 2021 13:12:40 +0200 Subject: [PATCH] generic: kernel 5.4: fix probe error for AR803x PHYs Atheros PHYs using the at803x driver apart from the AR8031/AR8033 fail to probe with kernel 5.4, due to ret in at803x_probe being uninitialized. [ 1.403461] Atheros 8035 ethernet: probe of 4ef600c00.ethernet:01 failed with error -1066114012 Initialize ret in order to successfully prove the PHYs on kernel 5.4. Kernel 5.10 is not affected, as the ret is always assigned prior to returning. Tested on OCEDO Koala.
