Merge tag 'staging-3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging tree changes from Greg Kroah-Hartman:
"Here is the big staging tree pull request for the 3.5-rc1 merge
window.
Loads of changes here, and we just narrowly added more lines than we
added:
622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out
of the staging tree, to their respective "real" portions of the
kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new
drivers added to the tree:
- new iio drivers
- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers
All of the movements around have acks from the various subsystem
maintainers, and all of this has been in the linux-next tree for a
while.
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
Fixed up various trivial conflicts, along with a non-trivial one found
in -next and pointed out by Olof Johanssen: a clean - but incorrect -
merge of the arch/arm/boot/dts/at91sam9g20.dtsi file. Fix up manually
as per Stephen Rothwell.
