This fixes regression introduced in commit a37c82a3b3c0910019abfd22a97be1f ("clk: samsung: exynos4: Remove SRC_MASK_ISP gates"). Without this change exynos4 fimc-is driver fails to probe with an error log: [ 1.842447] ERROR: could not get clock /camera/fimc-is@12000000:uart(13) [ 1.848529] exynos4-fimc-is 12000000.fimc-is: failed to get clock: uart [ 1.855275] exynos4-fimc-is: probe of 12000000.fimc-is failed with error -2 Signed-off-by: Sylwester Nawrocki --- Kukjin, could you take this patch into your tree ? I have been applying it for several kernel releases now to get the Exynos4 FIMC driver even passing probing.
