Russell (or someone else), can you Ack this patch? I'd like to get this for 4.20.

It isn't yet part of drm-misc? It would make sense IMHO.
And 'due course' is too vague since this should be merged for 4.20. I plan to add BeagleBone Black support soon for 4.20 since the GPIO issues that blocked supporting that board are close to being resolved. And this should be fixed before enabling BBB support.
It's an annoying bug that trips up the cec-compliance adapter test.

I think not formally, drm/i2c isn't one of the drm-misc areas. But it does fall under "everything else" exception. And I'd be happy to ack a formal MAINTAINERS patch (plus maybe even moving it from drm/i2c/ to drm/bridge/).
And 'due course' is too vague since this should be merged for 4.20. I plan to add BeagleBone Black support soon for 4.20 since the GPIO issues that blocked supporting that board are close to being resolved. And this should be fixed before enabling BBB support.

Given that we are at 4.19-rc3, and you are talking about it being merged during the _next_ merge window, there is plenty of time remaining that waiting another week or two for me to pick it up is not a problem.
In any case, my plan is to merge it for 4.19 since it appears to be a bug fix, albiet a minor one.

No problem, then I leave it to you to pick up.
'due course' can mean anything from tomorrow to next year, so that didn't help me :-)

It's a bug fix, but nothing in the kernel tree is currently using this AFAIK. The BBB would be the first to actually activate it. I'm fine with merging it in 4.19, but it is not strictly necessary.

Thanks for handling tdaxxxx.c in an efficient manner.
And to clarify: drm-misc is just an option that's out there, and you're obviously very much welcome to join (commit rights included ofc). I do personally think it's great to have an informal group maintainership like in drm-misc where people can easily jump in&out of helping out with specific drivers, but it's by no means mandatory. There's lots of options to effectively and efficiently collaborate.
Thanks, Daniel
