    Subject[PATCH AUTOSEL for 4.9 39/49] spi: sun4i: disable clocks in the remove function
    Date
    From: Takuo Koguchi <takuo.koguchi@gmail.com>

    [ Upstream commit c810daba0ab5226084a56893a789af427a801146 ]

    mclk and hclk need to be disabled. Since pm_runtime_disable does
    not disable the clocks, use pm_runtime_force_suspend instead.

    Found by Linux Driver Verification project (linuxtesting.org).
