drm/radeon: map registers at load time
Now that the radeon driver has suspend/resume functions, it needs to map its registers at load time or it will likely crash if a suspend operation occurs before the driver has been initialized. This patch moves the register mapping code from firstopen to load and makes the mapping into a _DRM_DRIVER one so that the core won't remove it at lastclose time. Fixes (at least partially) kernel bz #11891. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@linux.ie>
