Sajal Gupta cb732d027a drm/gud: validate GUD_ROTATION_0 is present in supported rotations ... The rotation argument to drm_plane_create_rotation_property() is set to DRM_MODE_ROTATE_0, and the device reported rotation bitmask is used as the supported_rotations argument. The driver never validates that GUD_ROTATION_0 is present, so a device that omits it from its GUD_PROPERTY_ROTATION triggers the WARN_ON(rotation & ~supported_rotations) in drm_plane_create_rotation_property() Fix this by skipping the creation of rotation property if the device doesn't have the GUD_ROTATION_0 bit Fixes: 40e1a70b4a ("drm: Add GUD USB Display driver") Reported-by: syzbot+efe2810681f1b065d3a8@syzkaller.appspotmail.com Closes: https://syzkaller.appspot.com/bug?extid=efe2810681f1b065d3a8 Tested-by: syzbot+efe2810681f1b065d3a8@syzkaller.appspotmail.com Signed-off-by: Sajal Gupta <sajal2005gupta@gmail.com> Acked-by: Ruben Wauters <rubenru09@aol.com> Signed-off-by: Ruben Wauters <rubenru09@aol.com> Link: https://patch.msgid.link/20260821071812.16500-1-sajal2005gupta@gmail.com		2026-08-23 17:35:13 +01:00
