Merge tag 'staging-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH:
"Here's the big staging tree pull request for 3.19-rc1.
We continued to delete more lines than were added, always a good
thing, but not at a huge rate this release, only about 70k lines
removed overall mostly from removing the horrid bcm driver.
Lots of normal staging driver cleanups and fixes all over the place,
well over a thousand of them, the shortlog shows all the horrid
details.
The "contentious" thing here is the movement of the Android binder
code out of staging into the "real" part of the kernel. This is code
that has been stable for a few years now and is working as-is in the
tens of millions of devices with no issues. Yes, the code is horrid,
and the userspace api leaves a lot to be desired, but it's not going
to change due to legacy issues that we have no control over. Because
so many devices and companies rely on this, and the code is stable,
might as well promote it out of staging.
This was all discussed at the Linux Plumbers conference, and everyone
participating agreed that this was the best way forward.
There is work happening to replace the binder code with something new
that is happening right now, but I don't expect to see the results of
that work for another year at the earliest. If that ever happens, and
Android switches over to it, I'll gladly remove this version.
As for maintainers, I'll be glad to maintain this code, I've been
doing it for the past few years with no problems. I'll send a
MAINTAINERS entry for it before 3.19-final is out, still need to talk
to the Google developers about if they are willing to help with it or
not, last I checked they were, which was good.
All of these patches have been in linux-next for a while with no
reported issues"
