    Subject[PATCH 6/6] regulator: anatop: set default voltage selector for pcie
    Date
    Set the initial voltage selector for vddpcie in case it's disabled
    by default.

    This fixes the below warning:
    20c8000.anatop:regulator-vddpcie: Failed to read a valid default voltage selector.
    anatop_regulator: probe of 20c8000.anatop:regulator-vddpcie failed with error -22
