A ring_index value of 0 is being used to reference the free buffer ring
fbr[1] and ring_index=1 is used to reference fbr[0]. Avoid this
confusing referencing by swapping the indicies so that ring_index=0
refers to fbr[0] and vice versa.

This driver uses the comedi PCI auto attach mechanism and the comedi
core does not use the boardinfo during the attach.

Now that this driver has the attach separated from addi_common.c we
can remove passing the boardinfo in the comedi_driver and cleanup
the code that finds the boardinfo.

Also, rename addi_find_boardinfo() so it has namespace associated
with this driver.

Only the apci3120 board supports an analog output subdevice. The
boardinfo indicates this by setting the 'i_NbrAoChannel' value.

operation are fixed for the analog outputs. Remove this information
from the boardinfo and use it directly in the subdevice init.

Merge tag 'iio-for-3.8b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Second round of new IIO drivers and cleanups for the 3.8 cycle.

Usual mixed bag of cleanups and minor improvements including
one reversion for a patch in the previous series.

* adt7310 and adt7410 drivers merged into one.
* Revert use devm_kcalloc in at91_adc (because it doesn't exist)
* unlocking fix for error path in the ad5449
* isl29018 suspend and resume support.
* improved pseudo floating point parsing for info_mask write
attributes (and hence into write_raw).  Reject some messed up
strings.

The driver leaves the device in power-down state anyway,
so there is nothing to do on suspend.
On resume, we just have to make sure the range and ADC
values are updated in the device since it may have been
powered down in suspend.

When parsing a fixed point number IIO stops parsing the string once it has
reached the last requested decimal place. This means that the remainder of the
string is silently accepted regardless, of whether it is part of a valid number
or not. This patch modifies the code to scan the whole string and only accept
valid numbers. Since fract_mult is 0 after the last decimal place any digit that
may follows won't affect the result.

Currently when parsing a fix-point number we silently skip any additional '.'

disallows this and returns an error if more than one '.' is encountered.

The `pci_enabled` member of `struct jr3_pci_dev_private` is used to
indicate whether the call to `comedi_pci_enable()` was successful.  The
'detach' routine `jr3_pci_detach()` uses this to decide whether to call
`comedi_pci_disable()`.  The `iobase` member of `struct comedi_device`
is not used by this driver so it can be used for the same purpose.

Remove the `pci_enabled` member and use the spare `dev->iobase` instead.
