Veera Sundaram Sankaran b8b095b57d disp: msm: sde: avoid multiple frame-done encoder events
Currently there is a race condition in checking the
pending_kickoff_cnt in wr_ptr_irq wait from display-thread
and pp_done_irq from interrupt context. In both places,
pending_kickoff_cnt is read first and modified later. In
partial update cases where the frame-transfer is short,
such a race condition might happen and would lead to both
triggering the frame-done/release fence for the same frame.
Fix it by combining read/modify to one statement in both places.
