[PATCH 03/15] drm/panfrost: don't use pfdevfreq.busy_count to know if hw is idle
From: ClÃment PÃron
Date: Sun May 10 2020 - 12:55:54 EST
This use devfreq variable that will be lock with spinlock in future
patches. We should either introduce a function to access this one
but as devfreq is optional let's just remove it.
