Thx for confirming. Yes, that patch is in the drm-misc-fixes tree as bf43e4521ff3 and thus will likely be merged with this weeks DRM merge. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
