Thank you for checking with sc7280. I created https://gitlab.freedesktop.=
org/drm/msm/-/issues/25 and CCed you. I've also verified that the error p=
ersists with v6.4.0-rc4 + Kuogee's patch (just in case you may have teste=
d on sc7280 with 6.4).

I see Bjorn also tested the patch. As it fixes a serious USB-C DP regress=
ion which broke USB-C DP completely on lazor for v6.3, can it be included=
 in upcoming 6.3.y release?

Thank you
Leonard
