The private data, struct local_info_t, is not being used in the
driver. Remove it as well as the kzalloc/kfree.
Also, don't set the 'pcmcia_cur_dev' variable unless the pcmcia
configuration is successful.

For aesthetic reasons, move all the pcmcia_driver functions so they
are near the pcmcia_driver declaration. This also removes the need
for some of the forward declarations.

The pcmcia_driver suspend and remove functions set the 'stop' variable
and the resume function clears it. Nothing in the comedi_driver code
uses the 'stop' variable.
Just remove it so we can get rid of the suspend/resume.

Remove the DPRINTK() function trace message as well as the #if 0'ed
out debug code that dumps the board "fingerprint".
Remove the need for the local variable that holds the link->irq
passed to request_irq(). Also, return the error code from that
function instead of assuming -EINVAL. Use the dev->board_name for
the resource string passed to request_irq() instead of the open
coded string "ni_mio_cs".
For aesthetic reasons, add some whitespace to the initializatio

In daqp_attach(), the first options value passed in the comedi_devconfig
is used as an index to the private dev_table[] in this driver. This table
is used to pass the pcmcia_device to the comedi_driver.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Second set of IIO new drivers, cleanups and fixes for the 3.9 cycle.
This second version is due to a little fixup for an include
path being added to the tsl2563 move out of staging after
a report from Fengguang Wu and the 0-day kernel build testing
backend.
Minor bits:
1) A Kconfig dependency fix for the max1363 driver that
has been causing some autobuilder fails in Linux Next.
2) Removal of a stale makefile entry
3) Fix an incorrect arguement for a sizeof call
4) Duplicate code removal in tsl2x7x driver
5) A missing spin lock init in hid-sensor-time
New features:
1) mxs adc driver gains support for touchscreen special functions
2) mxs driver gainst supprot for the MX23 and dt entries added
3) adis16400 gains adis16448 support and some additional bells and whistles
Moves out of staging.
1) adis16400 - a venerable driver gets a make over and moves
out of staging.
2) Kxsd9 moved out fo staging
3) adis16080 gets cleaned up and moved out of staging
4) tsl2563 gets a little cleaned up and move out of staging
Removals
1) sw_ring is killed off with all remaining drivers converted to kfifo.
This has been scheduled for a long time since we switched to kfifo.
There is demand for a high performance alternative, but this was
never it and I'm glad to see this vestage of IIOs youth gone once
and for all!

During sampling the driver currently does a spi_read followed by a spi_write.
This is not a problem per se, since CS needs to be deasserted between the two
transfers. So even if another device claims the bus between the two transfers we
should still get a result. But the code is actually spread out over multiple
functions. E.g. the spi_read happens in one function the spi_write in another,
this makes the code harder to follow. This patch re-factors the code to just use
a single spi transaction to do both the read and the write transfer.

The adis16100 is very similar to the adis16080. The driver description already
states that the driver supports the adis16100 as-well. But so far the there is
no device id table for the adis16100 and the drivers does not bind to a device
named adis16100.
