The '/**' here and on most of the other comments is deliberate.  It is 
used to mark things up with "kernel-doc" - see 
"Documentation/kernel-doc-nano-HOWTO.txt".

Admittedly, this wasn't a valid kernel-doc comment, but I'm planning to 
fix that shortly.

Please don't bother fixing this patch as I'm about to send a larger 
series of patches to comedidev.h to add more documentation and I will 
fix the incorrect block comments in that series.
