Subject: [PATCH] Revert "net: phy: fixed_phy: Fix NULL vs IS_ERR() checking in __fixed_phy_register"
Git-commit: 065e1ae02fbe5f56f4aa118414d45fc30647acd4
Patch-mainline: v5.16
References: git-fixes
This reverts commit b45396afa4177f2b1ddfeff7185da733fade1dc3 ("net: phy:
Fixed_phy: Fix NULL vs IS_ERR() checking in __fixed_phy_register")
since it prevents any system that uses a fixed PHY without a GPIO
descriptor from properly working:
[ 5.971952] brcm-systemport 9300000.ethernet: failed to register fixed PHY
[ 5.978854] brcm-systemport: probe of 9300000.ethernet failed with error -22
[ 5.986047] brcm-systemport 9400000.ethernet: failed to register fixed PHY
[ 5.992947] brcm-systemport: probe of 9400000.ethernet failed with error -22
