staging: comedi: comedi_fops: cleanup comedi_poll()

Browse source

Consolidate the local variables 'read_subdev' and 'write_subdev' into a
single local variable 's'.

Use comedi_dev_from_minor() to simplify the return -ENODEV tests.

Use a goto in the !dev->attached test so that the mutex_unlock() call
is in a common place.

Cleanup the formating of the || in the read and write subdevice poll
code.
