Use to_iio_trigger(dev) instead of dev_get_drvdata(dev). Both will return the
trigger which belongs to the device, but the the first on is a bit more
lightweight.
Since this is the last location where we used dev_get_drvdata() for retrieving
the trigger there is no need anymore to assign the the trigger to the devices
drvdata, so we can remove that as well.

for driver specific data.

The result of "foo = bar" is true, so in statements such as
...
if((pDevice->bwextstep0 = TRUE)&&(param->u.wpa_key.key_index ==1))
...
an assignment is most likely not what was intended - a comparison was. As in:
...
if ((pDevice->bwextstep0 == TRUE) && (param->u.wpa_key.key_index == 1))
...
There are a 3 such mistakes in the iwctl_siwencodeext() function.
This patch fixes them all.

Move the pcmcia_disable_device() call where needed in the
pcmcia attach/detach and delete the dio700_release() function.
Move the logic of dio700_config() directly into the attach
function and properly return an error code when the config
fails.
Only set the pcmcia_cur_dev, used by the comedi_driver, if
the pcmcia attach is successful. Also, make sure to NULL it
in the detach.
Remove all the kernel messages in the pcmcia support code. They
are just added noise.

The pcmcia support code in this driver appears to be cut-and-
paste from some other driver. It has code in it to stop the
device during suspend but nothing in the main comedi_driver
uses it.
Remove the 'stop' variable from the pcmcia private data and
all the logic that deals with it.

These messages should probably just be removed. For now just clean
then up.
Remove a couple redundant KERN_INFO messages in the pcmcia support
code and leave the dev_dbg() ones.
Change the dev_dgb() messages to use __func__ instead of the open
coded string.

The 'data[1] = ...' line is currently kept < 80 chars by breaking a pointer
access after the '->'. This makes the code a bit confusing to follow. Use
a local variable to shorten the line and make it clearer.

Use the dev_printk() routines to output the kernel messages in the
attach routine.
The main 'attach' message had a level of KERN_ERR, I believe it should
have been KERN_INFO. Also, move that message to the end of the attach
so it only gets displayed if the attach is successful.

This driver was originally copied from the 8255 driver. The 8255
uses a callback function to handle the io operations to the device.
In this driver, the callback adds unneeded complexity.
The CALLBACK_ARG for this driver is always 'dev->iobase' and the
CALLBACK_FUNC is always 'subdev_700_cb'.
The callback function is also overly complex for this driver.
It takes a 'dir' parameter to determine if the io is a write or
read, a 'port' parameter that is not used, a 'data' parameter
that is only used for writes, and an 'arg' which is the iobase
of the device.
Unwind all of it and just put the outb()/inb() call in the code
where needed.
This allows getting rid of the private data completely. Refactor
the code based on it's removal.

The 'thisboard' macro relies on a local variable having a specific

Replace the macro with local variables and use the comedi_board()
helper to get the pointer.

This driver exports a number of functions with EXPORT_SYMBOL()
but nothing actually uses them. They also are not declared in
any header for use outside this module.
As stated in the comments, this driver was based on the 8255
driver so these exports are most likely the result of cut-and-
paste from the 8255 driver.
Remove all the EXPORT_SYMBOL() lines. If the exported function
is not used in the driver, remove the entire function as well.
If the function is used, make it static.
Also, make the dio700_cs_driver variable static since it's only
referenced in this file.
This quiets the following sparse warnings:
warning: symbol 'subdev_700_interrupt' was not declared. Should it be static?
warning: symbol 'subdev_700_init' was not declared. Should it be static?
warning: symbol 'subdev_700_init_irq' was not declared. Should it be static?
warning: symbol 'subdev_700_cleanup' was not declared. Should it be static?

The private DEBUG macro defined in this driver outputs a lot
of function tracing noise. This information might be useful
when first developing the driver but should not be in the
mainlined code.
If any of this is needed in the future it should be added back
using the proper dev_printk interface.
