I certainly haven't been paying attention. My excuse, at least, is that you're a great maintainer and I haven't thought the patches need a second look.

With drm_bridge, I've been lending review help, but deferring to Archit for merge on patches which I think he should look at. Gustavo is in a similar place with fences. drm_panel seems like something that should follow the same model.

I'm mostly thinking out load here, so take it for what it's worth.
