Looking at the prefix of Documentation/devicetree/bindings/sound/ commits, I'm always confused whether it's a pure binding commit or just submitted as part of the driver patch. I feel that we kinda lose the point of having a prefix. Just my 2 cents.

That's really not what's happening reliably - other subsystems also seem to have a bunch of things prefixed for the subsystem and the DT specific prefixes are all over the shop, people seem to be making them up at random. If DT binding review were something that reliably and consistently happened and didn't affect the subsystem I'd perhaps buy it but for run of the mill stuff it seems like getting things reviewed in the subsystem is more important.

I'm getting more picky about the subject and splitting bindings to a separate patch, but generally only when I have other comments. And I've had to get some maintainers to stop combining commits as they apply them. Maybe get_maintainers.pl could spit out the desired prefix and checkpatch check it. Evidently, running "git log --oneline" is too hard. > If DT binding review were something that reliably and > consistently happened and didn't affect the subsystem I'd perhaps buy it > but for run of the mill stuff it seems like getting things reviewed in > the subsystem is more important. I review everything that gets sent to the DT list unless maintainers apply it first. I'll still comment afterwards if there's anything significant (or I missed that it was applied :)).
