Subject: [patch 1/3] staging: fix comedi build when ISA_DMA_API is enabled but COMEDI_PCI is not enabled

From: Randy Dunlap <rdunlap@...otime.net>

Fix build when CONFIG_ISA_DMA_API is enabled but
CONFIG_COMEDI_PCI[_DRIVERS] is not enabled.
Fixes these build errors:

drivers/staging/comedi/drivers/ni_labpc.c: In function 'labpc_ai_cmd':
drivers/staging/comedi/drivers/ni_labpc.c:1351: error: implicit declaration of function 'labpc_suggest_transfer_size'
drivers/staging/comedi/drivers/ni_labpc.c: At top level:
drivers/staging/comedi/drivers/ni_labpc.c:1802: error: conflicting types for 'labpc_suggest_transfer_size'
drivers/staging/comedi/drivers/ni_labpc.c:1351: note: previous implicit declaration of 'labpc_suggest_transfer_size' was here
