Merge tag 'char-misc-5.4-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 pull request for 5.4-rc1.
As has been happening in previous releases, more and more individual
driver subsystem trees are ending up in here. Now if that is good or
bad I can't tell, but hopefully it makes your life easier as it's more
of an aggregation of trees together to one merge point for you.
Anyway, lots of stuff in here:
- habanalabs driver updates
- thunderbolt driver updates
- misc driver updates
- coresight and intel_th hwtracing driver updates
- fpga driver updates
- extcon driver updates
- some dma driver updates
- char driver updates
- android binder driver updates
- nvmem driver updates
- phy driver updates
- parport driver fixes
- pcmcia driver fix
- uio driver updates
- w1 driver updates
- configfs fixes
- other assorted driver updates
All of these have been in linux-next for a long time with no reported
issues"
