staging: comedi: comedi_pci: introduce comedi_pci_detach()
Introduce a generic (*detach) function for comedi PCI drivers to handle
the boilerplate code needed to detach a PCI driver.
This function works similar to comedi_legacy_detach() where it will:
* free the dev->irq if it has been requested
* iounmap the dev->mmio addres if it has been ioremap'ed
The helper then calls comedi_pci_disable() to release the regions and
disable the PCI device.
Use the new helper directly for the (*detach) in the following cases:
* where comedi_pci_disable() is used directly for the (*detach)
* where the detach function is just boilerplate
Use the new helper in the (*detach) of the simpler PCI drivers. Call
the helper after disabling interrupts (reset) and before any additional
cleanup (kfree) to avoid any race conditions with the interrupt handler.

Use the new 'mmio' member in the comedi_device for the ioremap'ed

Only the ni_labpc_pci module does the ioremap, its also the only
module that sets the 'has_mmio' member in the boardinfo. Remove
this member from the boardinfo and use dev->mmio to determine if
the I/O is memory mapped.

staging: comedi: ni_labpc_pci: remove COMEDI_MITE and HAS_DMA dependancy
The mite module provides the DMA interface for the PCI MITE ASIC used on
many National Instruments DAQ boards. This driver does not use DMA and only
depends on the mite module to initialize the MITE ASIC.
Handle the initialization localy and remove the unnecessary dependancies.

staging: comedi: mite: cleanup mite_unsetup()
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.

staging: comedi: mite.h: remove mite_irq()
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.

staging: comedi: don't rely on comedidev.h to include headers
comedidev.h is the main kernel header for comedi. Every comedi
driver includes this header which then includes a number of
<linux/*> headers. All the drivers need <linux/module.h> and some
of them need <linux/delay.h>. The rest are not needed by any of
the drivers.
Remove all the includes in comedidev.h except for <linux/dma-mapping.h>,
which is needed to pick up the enum dma_data_direction for the
comedi_subdevice definition, and "comedi.h", which is the uapi
header for comedi.
Add <linux/module.h> to all the comedi drivers and <linux/delay.h>
to the couple that need it.

staging: comedi: drivers: let core handle freeing s->private
Introduce a new subdevice runflags, SRF_FREE_SPRIV, and a new helper
function, comedi_set_spriv(), that the drivers can use to set the
comedi_subdevice private data pointer. The helper function will also
set SRF_FREE_SPRIV to allow the comedi core to automatically free the
subdevice private data during the cleanup_device() stage of the detach.
Currently s->private is only allocated by the 8255, addi_watchdog,
amplc_dio200_common, and ni_65xx drivers. All users of those drivers
can then have the comedi_spriv_free() calls removed and in many cases
the (*detach) can then simply be the appropriate comedi core provided
function.
The ni_65xx driver uses a helper function, ni_65xx_alloc_subdevice_private(),
to allocate the private data. Refactor the function to return an errno
or call comedi_set_spriv() instead of returning a pointer to the private
data and requiring the caller to handle it.

staging: comedi: ni_labpc: remove *_ai_gain_bits tables
The bits needed to set the analog input gain can be simply calculated
based on the 'range'.
The LabPC versions of the board do not have the '0x10' gain that the
LabPC+ board supports. By incrementing the range appropriately the
correct gain bits can still be calculated.
This allows removing the two gain tables, as well as the export, along
with the 'ai_range_code' data in the boardinfo.

The 'register_layout' in the boardinfo can be represented as

The 'has_ao' variable is also a true/false flag. Change it to

Reorder the boardinfo data so that the bit-field data is grouped
together.
For aesthetic reasons, and move the 'const' variables then
reorder the boardinfo declarations to match the definition.

staging: comedi: ni_labpc: split out PCI support
Currently the ni_labpc driver is used by the legacy (ISA), PCI, and
PCMCIA versions of the LabPC board. The driver is enabled under the
COMEDI_PCI_DRIVERS section of the Kconfig. This means that PCI support
must be enabled in order to use the ni_labpc driver for the PCI or
PCMCIA drivers.
Split the PCI support code out of the ni_labpc driver into a separate
driver, ni_labpc_pci. The PCMCIA support is already slip out as
ni_labpc_cs.
Modify the Kconfig so that the common code in ni_labpc is enabled by the
Kconfig option COMEDI_NI_LABPC. The ISA support code is currently still
in the ni_labpc driver but is only compiled in if COMEDI_NI_LABPC_ISA is
also enabled.
This allows the PCI and PCMCIA drivers to be enabled without the need
for the ISA stuff.
