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. * tag 'staging-3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (536 commits) Staging: bcm: Remove two unused variables from Adapter.h Staging: bcm: Removes the volatile type definition from Adapter.h Staging: bcm: Rename all "INT" to "int" in Adapter.h Staging: bcm: Fix warning: __packed vs. __attribute__((packed)) in Adapter.h Staging: bcm: Correctly format all comments in Adapter.h Staging: bcm: Fix all whitespace issues in Adapter.h Staging: bcm: Properly format braces in Adapter.h Staging: ipack/bridges/tpci200: remove unneeded casts Staging: ipack/bridges/tpci200: remove TPCI200_SHORTNAME constant Staging: ipack: remove board_name and bus_name fields from struct ipack_device Staging: ipack: improve the register of a bus and a device in the bus. staging: comedi: cleanup all the comedi_driver 'detach' functions staging: comedi: remove all 'default N' in Kconfig staging: line6/config.h: Delete unused header staging: gdm72xx depends on NET staging: gdm72xx: Set up parent link in sysfs for gdm72xx devices staging: drm/omap: initial dmabuf/prime import support staging: drm/omap: dmabuf/prime mmap support pstore/ram: Add ECC support pstore/ram: Switch to persistent_ram routines ...
