Subject: staging: comedi: dt282x: remove 'volatile' on private data variables
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ebf86ea9a68e2ebb366dc7640f916e233d614db1;p=deliverable%2Flinux.git

staging: comedi: dt282x: 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.
