drm/atmel-hlcdc: don't reject the commit if the src rect has fractional parts

Browse source

[ Upstream commit 06682206e2 ]

Don’t reject the commit when the source rectangle has fractional parts.
This can occur due to scaling: drm_atomic_helper_check_plane_state() calls
drm_rect_clip_scaled(), which may introduce fractional parts while
computing the clipped source rectangle. This does not imply the commit is
invalid, so we should accept it instead of discarding it.
