Merged to -next, thanks.

The drm printer stuff looks really promising!  I'm also interested,
though, in the debugfs_regset32 stuff that lets you just name your regs
in a struct and pass it and your regs base address to the helper for
creating the debugfs entry.  I bet we can mash those two ideas together
into something really nice.
