Linus Torvalds 751144271f staging tree merge for 3.12-rc1
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.

Lars-Peter Clausen 3edc84e605 iio: Add a comment to about alphabetical order to Kconfigs and Makefiles
Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of

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.

Johan Hovold 9c8ea1b29b iio: add LM3533 ambient-light-sensor driver
Add sub-driver for the ambient-light-sensor interface on National
Semiconductor / TI LM3533 lighting power chips.

The sensor interface can be used to control the LEDs and backlights of
the chip through defining five light zones and three sets of
corresponding output-current values.

The driver provides raw and mean adc readings along with the current
light zone through sysfs. A threshold event can be generated on zone
changes. The ALS-control output values can be set per zone for the three
current output channels.
