Hi,

After implementing genpd framework for EXYNOS4, (Ref commit 91cfbd4
"ARM: EXYNOS: Hook up power domains to generic power domain
infrastructure" in Kukjin's for-next branch), we are getting following
warning from s5p-hdmi driver.

The test was done on Origen board with code based on 3.3-rc4 and
Kukjin's for-next branch. [1]
