drm/msm/dpu: correct dpu_plane_virtual_atomic_check()

[PATCH] drm/msm/dpu: correct dpu_plane_virtual_atomic_check()

Posted by Dmitry Baryshkov 2 months, 3 weeks ago

Fix c&p error in dpu_plane_virtual_atomic_check(), compare CRTC width
too, in addition to CRTC height.

Fixes: 8c62a31607f6 ("drm/msm/dpu: allow using two SSPP blocks for a single plane")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202507150432.U0cALR6W-lkp@intel.com/
