Merge tag 'char-misc-4.18-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 and misc driver patches for 4.18-rc1.
It's not a lot of stuff here, but there are some highlights:
- coreboot driver updates
- soundwire driver updates
- android binder updates
- fpga big sync, mostly documentation
- lots of minor driver updates
All of these have been in linux-next for a while with no reported
issues"
