Subject[PATCH v12 07/10] drm/msm/dpu: always clear every individual pending flush mask
Date
There are two tiers of pending flush control, main controller and
individual hardware block. Currently only the main controller of
flush mask is reset to 0 but leave out some individual pending flush
mask of particular hardware block keep previous value at
clear_pending_flush(). Reset all individual hardware blocks flush
mask to 0 to avoid individual hardware block be triggered accidentally.
