This will fail for the pinmux group, but doesn't cause any harm, as the failure is ignored silently. However, after "pinctrl: sh-pfc: propagate errors on group config", the failure will become fatal, leading to a broken display: sh-pfc e6050000.pin-controller: pin_config_group_set op failed for group 102 sh-pfc e6050000.pin-controller: Error applying setting, reverse things back sh-pfc e6050000.pin-controller: failed to select default state Move the GPIO hog to its own node to fix this.
