+ Say Y here if you have a SUNIX Multi-IO card.
+
+ To compile this driver as a module, choose M here: the
+ module will be called snx.

why exactly do you introduce driver-specific ioctls ?
what is "ACS"

GPIO stuff belongs into the gpio subsystem. see drivers/gpio/

oh, not good. the struct tty_driver should be contained in
snx_ser_driver (not a pointer to it). or the other way round:
give the tty driver a pointer to a driver-private struct.

and this data looks as it should be assigned to individual
devices, not to driver globally.

parport, serial port, gpio should be separate drivers.

please try not to use global fields. these things look they belong into
the corresponding device private data structs.

does that really need to be in a header file ?

do these functions really *need* to be in the header and static inline ?
(IOW: are they really needed from multiple .c files ?)
