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.

iio: isl29018: Support suspend and resume.
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.

iio: Reject trailing garbage when parsing fixed point numbers
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.

iio: Do not accept multiple '.' in fixed point numbers
Currently when parsing a fix-point number we silently skip any additional '.'
found in the string. E.g. '1.2.3.4' gets parsed as '1.234'. This patch
disallows this and returns an error if more than one '.' is encountered.

Reformat the comment used to describe the Comedi driver to use the usual
block comment style.
Update the information reflecting the fact that the driver no longer
supports manual attachment of devices via the `COMEDI_DEVCONFIG` ioctl
and `attach()` method.
Also, in the instructions indicating where to put the firmware file,
mention the expected name of the file since the driver requests the
firmware file by name.

This driver is an example of how to write a Comedi driver and includes
some code for handling PCI devices, but not very much. It calls
`comedi_pci_auto_config()` at PCI probe time. That normally expects to
call the comedi driver's `auto_attach()` hook (or the deprecated
`attach_pci()` hook), but will fall back to using the `attach()` hook
that should only be used for attaching devices "manually" via the
`COMEDI_DEVCONFIG` ioctl.
Add an `auto_attach()` hook (`skel_auto_attach()`) to handle
auto-attachment of supported PCI devices. Add comments to the
`attach()` hook (`skel_attach()`) to indicate that it shouldn't
generally allow PCI devices to be attached that way (and probably isn't
needed at all for PCI-only Comedi drivers). Add code to the `detach()`
hook (`skel_detach()`) to disable PCI devices enabled by the
`auto_attach()` hook.
`skel_auto_attach()` calls new function `skel_find_pci_board()` to find
a matching element in `skel_boards[]`. PCI device ID information has
been added to `skel_boards[]` to give the function something to look
for.
