Subject: USB: ohci-at91: prepare clk before calling enable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8e82d8d98addfecf83c9d42ca78294a8d16070b9;p=linux-beck.git

USB: ohci-at91: prepare clk before calling enable

Replace clk_enable/disable with clk_prepare_enable/disable_unprepare to
avoid common clk framework warnings.
