42e4472ef1 staging: comedi: ni_labpc_cs: convert to auto attach
Convert this pcmcia driver to the comedi auto attach mechanism.

This allows getting rid of the "hack" needed to pass the pcmcia_device
pointer from the pcmcia_driver to the comedi_driver.

We still need the boardinfo because the ni_labpc driver uses it. But
we can get rid of the duplicate that allowed attaching with the driver
name.

89d714ce63 staging: comedi: ni_daq_dio24: remove some unnecessary includes
This driver does not use anything from the interrupt.h, slab.h,
and ioport.h headers. Don't bother including them.

For aesthetic reasons, move the include of the comedi specific
8255.h header to the end of the includes.

5a1daad46a staging: comedi: ni_daq_dio24: convert to auto attach
Convert this pcmcia driver to the comedi auto attach mechanism.

This allows getting rid of the "hack" needed to pass the pcmcia_device
pointer from the pcmcia_driver to the comedi_driver as well as the
now unnecessary boardinfo.

Check the call to subdev_8255_init() for success. That function does
a kzalloc and could return -ENOMEM.

6746dc6340 staging: comedi: ni_daq_dio24: cleanup dio24_detach
Simplify the call to subdev_8255_cleanup() to remove the
need for a local variable.

This driver only attaches to pcmcia devices so the test for
thisboard != pcmcia_bustype will always fail. Remove the test
and the unreachable release_region().

This driver also never does a request_irq() so remove the
free_irq().

fb89942cb3 staging: comedi: ni_daq_dio24: remove thisboard macro
The 'thisboard' macro relies on a local variable having a specific
name and yields a pointer derived from that local variable.

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

Absorb the code from dio24_config() into the probe function,
dio24_cs_attach() and properly return the error code when the
probe fails. This also gets rid of an unnecessary forward
declaration.

For aesthetic reasons, move the remove functio, dio24_cs_detach(),
so it's after the probe function.

Remove a number of dev_{level} noise messages in the probe/remove
functions.

This patch is for just moving plat-s3c24xx/*.c into mach-s3c24xx/, so
that we could remove plat-s3c24xx directory. But since the PLAT_S3C24XX

out next time.
