Subject: [PATCH 01/12] net: arc_emac: Fix memleak in arc_mdio_probe
Git-commit: e2d79cd8875fa8c3cc7defa98a8cc99a1ed0c62f
Patch-mainline: v5.9-rc4
References: git-fixes
When devm_gpiod_get_optional() fails, bus should be
freed just like when of_mdiobus_register() fails.
Fixes: 1bddd96cba03d ("net: arc_emac: support the phy reset for emac driver")
