[PATCH 0/2] staging: comedi: hide subdevice runflags stuff

[Ian Abbott <abbotti@mev.co.uk>]

Keep the details of the comedi subdevice `runflags` member local to
"comedi_fops.c".  In particular, the usage of the
`COMEDI_SRF_FREE_SPRIV` run-flag doesn't really fit in all that well
with the others.  It's used as a marker to indicate the subdevice's
`private` pointer can be automatically freed by the subdevice
clean-up code, whereas the others are associated with the operation of
asynchronous comedi commands.  Abstract it's usage away in a couple of
new wrapper functions.

1) staging: comedi: wrap COMEDI_SRF_FREE_SPRIV usage
2) staging: comedi: move COMEDI_SRF_... macros to "comedi_fops.c"
