clk: samsung: exynos5433: Add IGNORE_UNUSED flag to sclk_i2s1
[ Upstream commit 25bdae0f1c6609ceaf55fe6700654f0be2253d8e ]
Mark the SCLK clock for Exynos5433 I2S1 device with IGNORE_UNUSED flag to
match its behaviour with SCLK clock for AUD_I2S (I2S0) device until
a proper fix for Exynos I2S driver is ready.
This fixes the following synchronous abort issue revealed by the probe
order change caused by the commit 93d2e4322aa7 ("of: platform: Batch
fwnode parsing when adding all top level devices")
