From 8accb8fdf6ea6e1e4eb513e88e06d629ed01103b Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Wed, 16 Nov 2016 07:04:53 -0200 Subject: [media] s5p-mfc: Ensure that clock is disabled before turning power off Move clock disabling before turning power off. This will enable later to add calls to clk_prepare/unprepare in the s5p_mfc_power_off() function to avoid keeping clocks prepared all the time when driver is bound.
