This patch fixes regression in audio subsystem on Odroid XU3/XU4 boards that appeared after commits: 'commit 647d04f8e07a ("ASoC: samsung: i2s: Ensure the RCLK rate is properly determined")' 'commit 995e73e55f46 ("ASoC: samsung: i2s: Fix rclk_srcrate handling")' 'commit 48279c53fd1d ("ASoC: samsung: i2s: Prevent external abort on exynos5433 I2S1 access")' Without this patch the driver gets wrong clock as the I2S function (op_clk) clock in probe() and effectively the clock which is finally assigned from DT is not being enabled/disabled in the runtime resume/suspend ops. Without the above listed commits the EXYNOS_I2S_BUS clock was always set as parent of CLK_I2S_RCLK_SRC regardless of DT settings so there was no issue with not enabled EXYNOS_SCLK_I2S.
