From 26e33048aad0486c98155b1406037f02fe70cb1b Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Mon, 3 Dec 2007 01:43:23 -0300 Subject: [PATCH] V4L/DVB (6706): pvrusb2: Remove use of volatile in command sequencer pvrusb2: Remove use of volatile for command sequencer; these variables are set by interrupt-context code and we check their state in such a manner that there should be no race conditions. This had originally been done out of paranoia, and I have since been convinced that the paranoia is not required.
