Merge tag 'char-misc-5.11-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 char/misc driver update for 5.11-rc1.
Continuing the tradition of previous -rc1 pulls, there seems to be
more and more tiny driver subsystems flowing through this tree.
Lots of different things, all of which have been in linux-next for a
while with no reported issues:
- extcon driver updates
- habannalab driver updates
- mei driver updates
- uio driver updates
- binder fixes and features added
- soundwire driver updates
- mhi bus driver updates
- phy driver updates
- coresight driver updates
- fpga driver updates
- speakup driver updates
- slimbus driver updates
- various small char and misc driver updates"
