Subject[PATCH] Staging: comedi: Fixing style issues
Date
From: Mark Pearson <markpearson_de@yahoo.de>

comedi_fops.c : Warning that externs should be avoided in .c files.
A forward function decleration was declared extern
although it was only used internally. Changed
decleration to static.
comedi.h : Fixed warning that storage class should be a the
begining of declerations.

Lindent ran on both files.
