Revision 0d8ce3ae37e9bcfacbbc750cabf892fa00bb720e authored by Marek Szyprowski on 08 March 2012, 01:28:56 UTC, committed by Inki Dae on 15 March 2012, 02:38:59 UTC 
drm/exynos: fix runtime_pm fimd device state on probe
 
A call to pm_runtime_set_active() forces device to be at the active
state and skips calling its runtime suspend/resume callbacks. This
results in a freeze with a new power domain code based on gen_pd. Fimd
driver does all required runtime power management calls, so this
pm_runtime_set_active call is buggy. This patch removes it and corrects
clock management in probe function (clocks are now enabled by
pm_runtime_get_sync() call).
