Subject: [media] s5p-mfc: Ensure that clock is disabled before turning power off
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8accb8fdf6ea6e1e4eb513e88e06d629ed01103b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[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.
