    Subject[PATCH 4.9 010/177] regulator: anatop: set default voltage selector for pcie
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Dong Aisheng <aisheng.dong@nxp.com>


    [ Upstream commit 9bf944548169f6153c3d3778cf983cb5db251a0e ]

    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
