From b76ff5ea1cf6fe648e7ce2b84e636f8a95849a0b Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Wed, 28 Oct 2015 10:44:04 +0100 Subject: drm/vmwgfx: Replace iowrite/ioread with volatile memory accesses Now that we use memremap instead of ioremap, Use WRITE_ONCE / READ_ONCE instead of iowrite / ioread.
