[PATCH 00/11] staging: comedi: move comedi_fc functionality into core

[Ian Abbott]

The "comedi_fc" module contains a few functions for use by several
low-level comedi drivers.  Since they are used by quite a few drivers,
it seems useful to migrate their functionality to the core "comedi"
module, renaming them in the process, while keeping the original
function names in "drivers/comedi_fc.h" available for now.  This set of
patches accomplishes that.

The next stages after this will be to migrate the remaining inline
functions from "drivers/comedi_fc.h" (possibly making them externally
exported functions, although they are rather short), and then to update
the low-level drivers to call the functions with the new names,
eliminating the need to include "comedi_fc.h".  Then
"drivers/comedi_fc.h" can be removed as well.

Note that PATCH 10 has a couple of checkpatch warnings due to
changing an existing block comment in non-standard block-comment style.

PATCH 11 has a checkpatch warning to check whether MAINTAINERS needs
updating.  It doesn't.

PATCH 11 might conflict with some other patch series that haven't been
committed yet.
