Merge tag 'char-misc-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH:
"Here is the big set of char/misc and other driver patches for 5.5-rc1
Loads of different things in here, this feels like the catch-all of
driver subsystems these days. Full details are in the shortlog, but
nothing major overall, just lots of driver updates and additions.
All of these have been in linux-next for a while with no reported
issues"
