Merge tag 'staging-6.7-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 updates for 6.7-rc1. A bit
bigger than 6.6 this time around, as it coincided with the Outreachy
and mentorship application process, so we got a bunch of new
developers sending in their first changes, which is nice to see.
Also in here is a removal of the qlge ethernet driver, and the
rtl8192u wireless driver. Both of these were very old and no one was
maintaining them, the wireless driver removal was due to no one using
it anymore, and no hardware to be found, and is part of a larger
effort to remove unused and old wifi drivers from the system.
The qlge ethernet driver did have one user pop up after it was
dropped, and we are working with the network mainainers to figure out
what tree it will come back in from and who will be responsible for
it, and if it really is being used or not. Odds are it will show up in
a network subsystem pull request after -rc1 is out, but we aren't sure
yet.
Other smaller changes in here are:
- Lots of vc04_services work by Umang to clean up the mess created by
the rpi developers long ago, bringing it almost into good enough
shape to get out of staging, hopefully next major release, it's
getting close.
- rtl8192e variable cleanups and removal of unused code and
structures
- vme_user coding style cleanups
- other small coding style cleanups to lots of the staging drivers
- octeon typedef removals, and then last-minute revert when it was
found to break the build in some configurations (it's a hard driver
to build properly, none of the normal automated testing catches
it.)
All of these have been in linux-next for a while with no reported
issues"
