This structure needs to always stick around, even if CONFIG_HOTPLUG
is disabled, otherwise we can oops when trying to probe a device that
was added after the structure is thrown away.

Thanks to Fengguang Wu and Bjørn Mork for tracking this issue down.

Merge tag 'v3.6-rc1-iio-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

IIO fixes for v3.6-rc1

These mostly consist of fixes from Lars-Peter Clausen that were
the first part of a large series reworking the drivers concerned.
Turns out these drivers had quite a wealth of minor bugs.

Also here are some build warning fixes for lm3533-als and
adjd_s111 (both new drives in this cycle).
Final elements are a a div factor overflow and a warning
related fix in a couple of Analog Devices drivers.

All in all nothing major, but a worthwhile bunch of short
fixes.

staging:iio:ad7780: Mark channels as unsigned

2012-08-16T19:24:37+00:00

The values reported by the AD7780 are unsigned with a binary offset:

	0x000000 is negative fullscale
	0x800000 is zeroscale
	0xffffff is positive fullscale

So mark the channel in the channel spec as unsigned rather than signed.

staging:iio:ad7192: Report offset and scale for temperature channel

2012-08-16T19:24:37+00:00

The temperature channel reports values in degree Kelvin with sensitivity of 5630
codes per degree. If the chip is configured in bipolar mode there is an
additional binary offset of 0x800000 and the sensitivity is divided by two.

Currently the driver does the mapping from the raw value to degree Celsius when
doing a manual conversion. This has several disadvantages, the major one being
that it does not work for buffered mode, also by doing the division by the
sensitivity in the driver the precession of the reported value is needlessly
reduced.

Furthermore the current calculation only works in bipolar mode and the current
scale is of by a factor of 1000.

This patch modifies the driver to report correct offset and scale values in
both unipolar and bipolar mode and to report the raw temperature value
for manual conversions.

staging:iio:ad7192: Report channel offset

2012-08-16T19:24:37+00:00

In bipolar mode there is a a binary offset of 2**(N-1) (with N being the number
of bits) on the reported value. Currently this value is subtracted when doing a
manual read. While this works for manual channel readings it does not work for
buffered mode. So report the offset in the channels offset property, which will
work in both modes.

staging:iio:ad7192: Mark channels as unsigned

2012-08-16T19:24:36+00:00

The values reported by the AD7793 are unsigned.
	In uniploar mode:
			0x000000 is zeroscale
			0xffffff is fullscale
	In bipolar mode:
			0x000000 is negative fullscale
			0x800000 is zeroscale
			0xffffff is positive fullscale

In bipolar mode there is a binary offset, but the values are still unsigned.

staging:iio:ad7192: Add missing break in switch statement

2012-08-16T19:24:35+00:00

Without the break statement we fall right through to the default case and return
an error value.
