The usage of strict_strtoul() is not preferred, because
strict_strtoul() is obsolete. Thus, kstrtoul() should be
used.

New drivers
1) A driver for ST microelectronics sensors. This driver already covers
a large set of new parts (20 gyros, accelerometer and magnetometers)
not currently covered by the existing drivers. The intent moving forward
is to merge this with the other drivers for similar parts already in tree.
The lis3l02dq driver currently in staging/iio will be trivial, the lis3
driver in misc more complex as it has a number of additional interfaces.
Any merging in of the lis3 driver will rely on the not currently
merged iio_input bridge driver and handling of freefall notifications
etc.
2) A driver for the itg3200 gyroscope.
Graduations from staging
1) Cleanup and move out of staging of the adxrs450 gyroscope driver. The
cleanup required was all minor but there were a couple of fixes hidden in
there.
Core and driver additions
1) Initial work from Guenter Roeck on device tree support for IIO's provider/
consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver.
The full device tree syntax is currently under discussion but should
follow shortly.
Cleanups and fixes
1) Remove a noop function __iio_update_buffer
2) Couple of small fixes and cleanups for the max1363

merge commit 17cb3be61b
seems to have resulted in two functions that were removed in
4389fbec5b reappearing.
Spotted due to a build kicking out
drivers/iio/adc/max1363.c:1486:12: warning: 'max1363_register_buffered_funcs_and_init' defined but not used
drivers/iio/adc/max1363.c:1521:13: warning: 'max1363_buffer_cleanup' defined but not used
This patch just removes them again.

Instead of requiring the map to unregister, simply unregister all map entries
associated with the given iio device. This simplifies map removal and also works
for maps generated through devicetree.

For chips with more than 8 bit ADC resolution, received data was always
masked against 0xfff, ie with a 12 bit mask. This can result in bad data
for chips with 10 bit resolution if those chips have higher bits set
(seen with MAX1139).
The receive buffer was defined as char array. This could result in
unintentional sign extensions if the upper bit in a received byte
was set. Since the chip is configured for unipolar mode, we never
have to handle negative values, and sign extensions are never needed.

Here are a number of small fixes to staging drivers for your 3.8-rc3
tree.
Well, the omapdrm fixes aren't really "small" but they were waiting on a
number of other drm patches to go in through the drm tree, and got
delayed by my vacation over the holidays. They are totally
self-contained, everyone involved have acked them, and they fix issues
that people have been having with the driver.
Other than that one, it's a bunch of tiny bugfixes for a number of
reported issues.

It also allows the fwserial driver changes to be applied, as they
required the fixes that are in staging-linus.

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.

[39711.688835] Oops: 0000 [#1] SMP
Caused by bad probe error path. Fix it.
Driver should also not attempt to free the interrupt in its error path if
none was allocated. Fix that problem as well.
Finally, testing if the regulator was allocated is not necessary in the
remove function, since the probe function bails out if this is the case.
Remove that check.
