Pull staging tree merge from Greg KH:
"Here's the bit staging tree pull request for 3.12-rc1.
Lots of staging driver updates, and fixes. Lustre is finally enabled
in the build, and lots of cleanup started happening in it. There's a
new wireless driver in here, and 2 new TTY drivers, which cause the
overall lines added/removed to be quite large on the "added" side.
The IIO driver updates are also coming through here, as they are tied
to the staging iio drivers"

The original info_mask is going away in favour of the broken out versions.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Route all buffer writes through the demux.
Addition or removal of a buffer results in tear down and
setup of all the buffers for a given device.

Drop timestamp parameter from buffer store_to callback and subsequently from
iio_push_to_buffer. The timestamp parameter is unused and it seems likely that
it will stay unused in the future, so it should be safe to remove it.

Do not leak memory by updating pointer with potentially NULL realloc return value.
There is no need to preserve data in the buffer,
so replace krealloc() by kfree()-kmalloc() pair.

sensor has 4 channels (10-bit each, R/G/B and clear), sensitivity
and gain is controlled in the driver by ext_info integration_time
and CHAN_INFO_HARDWAREGAIN
driver supports triggered buffer and IIO_CHAN_INFO_RAW to get the
sensor data
v5: address comments by Jonathan Cameron
* use macro for channel declaration
* get timestamp right before measurement
* cleanups
v4: address comments by Lars-Peter Clausen
* make sure trigger handler is exited with iio_trigger_notify_done()
and IRQ_HANDLED
* kfree()/kalloc() -> krealloc()
v3:
* fix warnings
v2: address comments by Lars-Peter Clausen
* buffer allocation now in update_scan_mode instead of in trigger
handler
* simplify trigger code (assume active_scan_mask is not empty, use
for_each_set_bit, use iio_push_to_buffer)
* reorder entry in Makefile and Kconfig
* fix remove
