Subject: [PATCH 1/5] Staging: comedi: addi-data: tidy up digital input register map defines in hwdrv_apci1564.c
This patch for hwdrv_apci1564.c fixes the register map defines for the
digital input registers such that they are all the real offsets to each
register, rather than a mix of real offsets and adders to those offsets.
Additionally, the defines have been renamed to assist with shortening
some lines in excess of 80 characters.
Further, some of the old defines were being used incorrectly in the
i_APCI1564_Reset() function. Upon swapping the old defines out for the
new ones in this function, their use has been corrected.

Greg, as promised, this is the most up-to-date patchset for hwdrv_apci1564.c.
Please disregard any outstanding unapplied patches from me for this file as this
5 patch set supersedes all previous patchsets I have submitted for this file.
Hartley, I have followed the advice you gave and broke up this patchset
accordingly. It'd be great if I could get a review! This serves as the
beginning of a much more substantial cleanup of this driver.
Thanks,
Chase
