Linus Torvalds 6cfae0c26b Char/Misc driver patches for 5.4-rc1 
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.
