Subject: mmc: sdhci: disable the clock in sdhci_pltfm_unregister()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83eacdfa2529b4ee97fe16a3a3a41d1b03465e13;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mmc: sdhci: disable the clock in sdhci_pltfm_unregister()

So we can avoid to sprinkle the clk_disable_unprepare() in many
drivers.
