This fixes up the usb1401.c file to remove the usage of err() (which is
gone), and the two-argument kmap_atomic() call, and the compat_ioctl
pointer warning.

The code now builds properly, there are lots of warnings still, but it's
a start.

This was imported from the
http://pub.ist.ac.at/~schloegl/src/ced1401/.git git repo at the request
of Alois.  The driver originally came from Cambridge Electronic Design
Ltd and was authored by Greg P Smith and others, but Alois did the
maintance work to get it into a semi-building state and pushed to get it
into the main kernel tree here.

These messages are just added noise.

They also cause some sparse warnings due to MAX_ASICS evaluating
as 1. This causes the local variable 'irq' to be 'unsigned int irq[1]',
which makes the 'irq[1]' access invalid.

Just remove the messages.

Merge tag 'iio-for-v3.7d' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

IIO new drivers, features and rework for the 3.7 cycle, 4th set.

Here we have

1) a set cleaning up and moving the ad7476 driver out of staging.
Support for a number of additional parts is also added to that driver.

2) cleanups from various people for the in kernel interface code as that
is getting more an more real use and hence people are picking up on
minor issues that made it through review.  Also a related useful set
of utility functions to avoid duplicate code for converting IIO
representations to other forms.

3) a new fractional type for our read_raw / write_raw functions.
  This allows avoiding loss of accuracy via the in kernel interfaces in some
  cases as well as being rather convenient for a lot of range -> scale
  conversions.

4) New AD5755 DAC driver.

5) Some Blackfin timer trigger improvements including hardware pulse control
for device triggering.

6) Support for the ad7091r in the ad7476 driver.

Add support for the ad7091r 12 bit ADC to the ad7476 driver. Although the
ad7091r is not really related to any of the other devices supported by this
driver, luckily for us there are not so many ways (which are not totally insane)
how sampling a single channel ADC via SPI can be implemented and support for the
ad7091r can be added to the driver with just a few adjustments.

The ad7091r requires an external "conversion start" pulse to start a sample
conversion. After the conversion has finished the result can be read via SPI. We
depend on a IIO trigger to generate this signal, as a result only sampling in
buffered mode and not in manual mode is available.

Add a function to read a processed value from a channel. The function will first
attempt to read the IIO_CHAN_INFO_PROCESSED attribute. If that fails it will
read the IIO_CHAN_INFO_RAW attribute and convert the result from a raw value to
a processed value.

The patch also introduces a function to convert raw value to a processed value
and exports it, in case a user needs or wants to do the conversion by itself.

For the iio_read_channel_raw and iio_read_channel_scale the kerneldoc comment
refers to an argument called "channel", while the argument is called "chan" in
the function signature. This leads to the following warnings from kerneldoc:

	Warning(include/linux/iio/consumer.h:71): No description found for parameter 'chan'
	Warning(include/linux/iio/consumer.h:71): Excess function parameter 'channel' description in 'iio_read_channel_raw'
	Warning(include/linux/iio/consumer.h:109): No description found for parameter 'chan'
	Warning(include/linux/iio/consumer.h:109): Excess function parameter 'channel' description in 'iio_read_channel_scale'

This patch adds support for the AD5755, AD5755-1, AD5757, AD5735, AD5737 16 and
14 bit quad-channel DACs. The AD5757/AD5737 only have current outputs, but
for the AD5755/AD5757 each of the outputs can be configured to either be a
voltage or a current output. We only allow to configure this at device probe
time since usually this needs to match the external circuitry and should not be
changed on the fly.

A few trivial formatting changes on merge.

 The datasheet name is defined in the IIO driver.
 On the other hand, the adc_channel_label is configured in
 the platform side.
 If the datasheet name is not matched with any adc_channel_label,
 the iio_channel_get() should be returned as error for preventing
 invalid channel data access.

 This can be handled either way.
 (a) checking null data when using it : in the xxx_read_raw()
 or
 (b) error returns when the channel is requested : this patch

 The IIO consumer can't use the channel with invalid channel spec.
 Therefore case (b) is more reasonable.
