From 6f63840447030b32662d8d425b36e8fabd7799cf Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 29 Jul 2013 13:56:59 -0700 Subject: [PATCH] staging: comedi: das16: remove 'volatile' on private data variables As indicated by checkpatch.pl, "WARNING: Use of volatile is usually wrong: ...". The variables in the private data that are marked volatile don't need to be. Remove the volatile.
