Subject: [linus:master] [drm/tests] 881e2a9cc1:
WARNING:at_drivers/gpu/drm/drm_rect.c:#drm_rect_calc_vscale[drm_kms_helper]
hi,
we reported
"[drm-misc:drm-misc-next] [drm/tests] 881e2a9cc1: dmesg.WARNING:at_drivers/gpu/drm/drm_rect.c:#drm_rect_calc_vscale[drm_kms_helper]"
on
https://lore.kernel.org/all/202305051332.b634bb9a-yujie.liu@intel.com/
when this commit is still on
git://anongit.freedesktop.org/drm/drm-misc drm-misc-next
now we noticed the issue still exists on mainline.
at the same time, we noticed this commit adds the test cases for
drm_rect_calc_vscale(),
and the WARNING is introduced by this new added test, however, from below
details, the test itself passed.
[ 200.796859][ T1925] ok 7 drm_test_rect_calc_vscale
we are not sure if this WARNING is expected or just trivial.
below detail report is just FYI.
