This function is only called by comedi drivers during the (*detach) of the
driver. After it is called mite_free() is always called to kfree the allocated
mite_struct pointer.

Rename this function to mite_detach() and merge the kfree() from mite_free()
into it.

Remove the unnecessary clearing of the mite variables since the mite pointer
is going to be kfree()'d anyway.

The mite_detach() function checks if the pointer is valid so remove the
unnecessary checks in the callers.

The check can also be removed in ni_660x since the ni_660x_free_mite_rings()
function does not actually need the 'mite' pointer.

This inline function simply returns the 'irq' of the struct pci_dev pointer
that is stored in struct mite_struct. This pci_dev pointer is the same as
the one that is already available in the (*auto_attach) functions where
mite_irq() is used.

Use the pci_dev pointer directly to get the irq and remove the unnecessary
inline function to remove the indirection.

These defines were probably intended to be used so that ni_mio_common.c
could detect if it was included by a driver that uses ioport or memory
mapped register access. This can actually be detected by checking if
the 'mite' member in the private data has been allocated.

Regardless, the symbols are not used. Just remove them.

By convention, the first member of the boardinfo is a 'const char *' to
the board name, especially for those comedi drivers that rely on the
comedi core to set dev->board_ptr to the entry matching the board name
when doing a legacy (*attach) to a comedi driver.

Modify the ni_board_struct appropriately for consistency, although the
board name is only used for informational purposes by this driver (only
the driver name is matched by the comedi core).

For aesthetics, also move the members in the boardinfo declarations.

Merge tag 'iio-for-3.17b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second round of new drivers and cleanups for IIO in the 3.17 cycle.

New drivers
* mcp4902, mcp4912 and mcp4922 SPI DAC driver.
* max1027, max1029 and max1031 SPI ADC driver.

Cleanups
* cm32181 - use devm APIs to simplify error paths.
* ak8975 - use devm APIs to simplify error paths.
* ad9850 - drop some unused defines and an unnecessary goto.
* hmc5843 - add missing devices to the device id table and the documentation.
* ad9832 - small formatting cleanups.
* sca3000 - hide direct use of the stufftoread element by adding a
    data_available function.  This is a precursor for the addition of buffer
    watermarks to the subsystem but stands as a good cleanup on its own.

Change sca3000_ring implementation so that it exports a data_available
function to iio.
