Dan Carpenter 3e69837551 drm/i915/overlay: Prevent divide by zero bugs in scaling ... commit 90a3d22ff0 upstream. Smatch detected a divide by zero bug in check_overlay_scaling(). drivers/gpu/drm/i915/display/intel_overlay.c:976 check_overlay_scaling() error: potential divide by zero bug '/ rec->dst_height'. drivers/gpu/drm/i915/display/intel_overlay.c:980 check_overlay_scaling() error: potential divide by zero bug '/ rec->dst_width'. Prevent this by ensuring that the dst height and width are non-zero.
