[ Upstream commit 92d43bd3bc9728c1fb114d7011d46f5ea9489e28 ]
ipu_src_rect_width() was introduced to support odd screen resolutions such as 1366x768 by internally rounding up primary plane width to a multiple of 8 and compensating with reduced horizontal blanking. This also caused overlay plane width to be rounded up, which was not intended. Fix overlay plane width by limiting the rounding up to the primary plane.
drm_rect_width(&new_state->src) >> 16 is the same value as drm_rect_width(dst) because there is no plane scaling support.
