Merge tag 'for-v3.19-exynos-clk-2' of git://linuxtv.org/snawrocki/samsung into clk-next

- exynos4415 and exynos audio subsystem clk driver (build
  with PM_SLEEP disabled, resource release) fixes
- minor cleanups in drivers/clk/samsung/clk.c (spelling,
  includes)
- modification of the exynos4 HDMI PHY clock definition to
  model dependency of "sclk_hdmiphy" on the "hdmi" clock
