As suggested by Ian Abbott, comedi_set_spriv() can only be used to
set the subdevice->private pointer to something that can be kfree()'d.
Rename the function to comedi_alloc_spriv() and have it kzalloc() the
memory as well as set the private pointer. This saves a function call
in the drivers and avoids the possibility of incorrectly calling
comedi_set_spriv() for some pointer that is not meant to be kfree()'d.

The analog input subdevice support functions in hwdrv_apci3xxx.c
do not follow the comedi API.
The (*insn_config) function overrides the INSN_CONFIG_DIO_INPUT
instruction as an internal APCI3XXX_CONFIGURATION instruction. The
APCI3XXX_CONFIGURATION instruction requires 4 data parameters but
the comedi core sanity checks the INSN_CONFIG_DIO_INPUT instruction
which only has 1 data parameter. Because of this the (*insn_config)
function can never be called.
The (*insn_read) function is supposed to do "one-shot" or "software-
triggered" reads and return the data. The function in hwdrv_apci3xxx.c
does do this but it also is used to optionally start a "hardware-
triggered" conversion. Hardware-triggered conversions should be done
with the comedi_async command functions.
Delete the hwrdv_apci3xxx.c file and fix the analog input subdevice
in the driver by:
1) add a new (*insn_read) function for "one-shot" reads
2) implement the (*do_cmdtest) and (*do_cmd) functions for
"hardware-triggered" asyncronous reads
3) fix the interrupt handler to return the read data via the
