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"
