staging: comedi: pcl730: tidy up pcl730_do_insn()

Browse source

For aesthetic reasons, rename the function.

Use a local variable for the 'reg' offset that is stored in the
comedi_subdevice 'private' pointer to minimize the number of casts.
Also, add local variables for the 'mask' and 'bits'.

The outputs only need to be updated if the 'mask' indicates that the
'bits' are changing. Move the update code into the main 'if (mask)'
block.
