Hmm, no reply from Dmitry here or any other mail from him on lore since
a week. No big deal, but nevertheless a bit unfortunate, as I totally
agree: it would be really good to get this regressions fixed rather
sooner than later.

Is there any in-official de-facto co-maintainer for input that could
help out? CCing Jonathan, who according to get_maintainer.pl regularly
contributes to the input subsystem.

Guess if nothing happens soon I'll ask Linus to merge those two changes
directly, maybe he'll take them.

Ciao, Thorsten
