[PATCH v3 0/5] staging: comedi: addi_apci_1564: fix Change-of-State interrupt functionality

[Chase Southwood <chase.southwood@gmail.com>]

This patchset introduces a new private data struct for this driver, adds
all of the code required to support Change-of-State interrupts for the
digital input subdevice, and finally fixes
apci1564_interrupt() to service this type of interrupt correctly.

CHANGES FROM v1:
*leave the send_sig() calls in for now, until the proper replacement can
be implemented.
*removed unused static globals, removed the remaining one into the private
data struct.
*private data struct moved into addi_apci_1564.c.
*patches 4/6 and 5/6 from v1 have been merged into patch 4/5 here.
*(*cancel) for the interrupt subdevice has been reduced to just disable DI
interrupts rather than using the board's reset function.
*support for all interrupts issued by the board has been kept in
apci1564_interrupt(), rather than stripping everything out except for DI
interrupt support.  However, DI interrupt support has still been fixed.

CHANGES FROM v2:
*Just refreshed set against staging-next.  Otherwise everything is
exactly the same, and should apply now.
