Merge tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO updates from Greg KH:
"Here is the big staging tree update for 4.12-rc1.
It's a big one, adding about 350k new lines of crap^Wcode, mostly all
in a big dump of media drivers from Intel. But there's other new
drivers in here as well, yet-another-wifi driver, new IIO drivers, and
a new crypto accelerator.
We also deleted a bunch of stuff, mostly in patch cleanups, but also
the Android ION code has shrunk a lot, and the Android low memory
killer driver was finally deleted, much to the celebration of the -mm
developers.
All of these have been in linux-next with a few build issues that will
show up when you merge to your tree"
Merge conflicts in the new rtl8723bs driver (due to the wifi changes
this merge window) handled as per linux-next, courtesy of Stephen
Rothwell.
