From 43bd33f22444868cbc9d4cbec7a3efb0a7c2cb25 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 19 Dec 2012 15:33:29 -0700 Subject: staging: comedi: don't expose comedi_get_{read, write}_subdevice These two inline helper function in comedidev.h are only used in comedi_fops.c. They return information that should only be used by the comedi core. Move both functions to comedi_fops.c so they aren't exposed to the comedi drivers. Also, remove the inline tag and let the compiler figure it out.
