[PATCH] mmc: mtk-sd: Fix missing clk_disable_unprepare in msdc_of_clock_parse()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The clk_disable_unprepare() should be called in the error handling
of devm_clk_bulk_get_optional, fix it by replacing devm_clk_get_optional
and clk_prepare_enable by devm_clk_get_optional_enabled.

Fixes: f5eccd94b63f ("mmc: mediatek: Add subsys clock control for MT8192 msdc")
