This seems like a cut and paste bug. Smatch complains that we don't
allocate enough memory for a set_stakey_rsp struct. In fact this is
used as a set_assocsta_rsp struct throughout and that also matches the
name of the function.

Fix the use of insn->chanspec with the CR_CHAN, CR_RANGE, and CR_AREF
macros. insn->chanspec is an unsigned int not an array.
Cleanup the comments when creating the 'val' to write to the channel
list fifo so that the code is a bit more readable.
Use the 'val' variable when getting the value from the ADC fifo and
then munging the data. This cleans up the goofy line breaks.
This function still does not follow the expectations of the comedi core.
It is supposed to read insn->n values from the channel and return those
values. Currently it only reads a single value.

This function only needs to update the output channel state when
the 'mask' (data[0]) indicates that the state is changing. It's
also supposed to return the state for all the input and output
channels in data[1].
This function appears to work correctly but it's coded quite
differently form the other comedi drivers. Rework the function so
it follows the normal form. Also, use a couple local variables
for the mmio addresses used to read/write the dio ports.

This function is supposed to write to a single analog output channel.
The channel number is packed in insn->chanspec, which is an unsigned
int, and unpacked using the CR_CHAN() macro.
Currently this function is trying to use the chanspec as an array.
This works only if a single value is written.
Fix the function so that the desired channel is determined and all
the data is written to that channel.
Also, fix the return. The comedi core expects insn_read functions to
return the number of data values (insn->n).
