[PATCH] drm/i915: Remove unneeded double drm_rect_visible call in check_overlay_dst

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




check_overlay_dst for clipped is called 2 times: in drm_rect_intersect and than directly. Change second call for check of drm_rect_intersect result to save some time (in locked code section).

Found by Linux Verification Center (linuxtesting.org) with SVACE.
