    Subject[PATCH 4.14 225/251] mips: lantiq: add support for clk_get_parent()
    Date
    From: Randy Dunlap <rdunlap@infradead.org>

    [ Upstream commit fc1aabb088860d6cf9dd03612b7a6f0de91ccac2 ]

    Provide a simple implementation of clk_get_parent() in the
    lantiq subarch so that callers of it will build without errors.

    Fixes this build error:
    ERROR: modpost: "clk_get_parent" [drivers/iio/adc/ingenic-adc.ko] undefined!

    Fixes: 171bb2f19ed6 ("MIPS: Lantiq: Add initial support for Lantiq SoCs")
