Recently someone else from Red Hat notified me that their dock had
stopped working in Fedora after the recent 5.6 kernel update. It turns
out that Fedora picked up a couple of extra post-5.6 fixes for MST
(these are the F32 shas):
* 7012f01efd65461c1adc93bfcdc015d95a940672
drm/dp_mst: Fix W=1 warnings
* 0cf94a193d2219c75d666c55abc8b5270550f87d
drm/dp_mst: Make drm_dp_mst_dpcd_write() consistent with drm_dp_dpcd_write()
* 89c111383b8bd08c6fed3c35f1a9c2bda7dd1c4b
drm/dp_mst: Fix drm_dp_check_mstb_guid() return code
The first patch in that series regressed a couple of things, and the
second two patches fixed said regressions - but there was still one
issue leftover that I didn't notice and fix until last week. I've
backported that patch so it can be included in F31/32.
