Merge tag 'staging-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH:
"Here's the big, really big, staging tree patches for 4.2-rc1.
Loads of stuff in here, almost all just coding style fixes / churn,
and a few new drivers as well, one of which I just disabled from the
build a few minutes ago due to way too many build warnings.
Other than the one "disable this driver" patch, all of these have been
in linux-next for quite a while with no reported issues"
