Merge tag 'staging-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH:
"Here is the big set of staging driver patches for 6.0-rc1.
Another round where we removed more lines of code than added, always a
nice progression. Some of that came from the movement of the vme code
back into staging, and removal of some other of the vme driver code as
there are no known users and it is very obsolete and unmaintained. It
can be added back easily if someone offers to maintain it.
Other than that this merge has lots of little things:
- huge cleanups for r8188eu driver
- minor cleanups for other wifi drivers
- tiny loop fixes for greybus code
- other small coding style fixes
All of these have been in linux-next for a while with no reported
issues"
