Greg,

I've been receiving (and reading!) these messages; I replied that I am
not maintaining a tree, and have no way of testing these patches (no
access to hardware.) I believe it unlikely that my situation will
change, and so I should probably be removed from the maintainers file.

No acked-by or anything; the patches are not "obviously correct" by
visual inspection; they may be right, but would require deeper
thinking about what is actually happening than I'm capable of at this
time; I'm a bit rusty with this code base, and might miss something
important.

p.s. you didn't see my earlier reply because I forgot to hit 'plain text reply'
