The proper one is to extract drm_dev.h (since drmP.h is horribly messy), but that's a lot more work. -Daniel > > Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> > Cc: Daniel Vetter <daniel.vetter@ffwll.ch> > Cc: Ben Skeggs <bskeggs@redhat.com> > Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> > --- > drivers/gpu/drm/drm_fb_helper.c | 6 +++--- > drivers/gpu/drm/nouveau/nouveau_connector.c | 5 +++-- > drivers/gpu/drm/nouveau/nouveau_display.c | 6 +++--- > drivers/gpu/drm/nouveau/nouveau_fbcon.c | 3 ++- > include/drm/drm_atomic.h | 13 +++++++++++++ > 5 files changed, 24 insertions(+), 9 deletions(-) > > diff --git a/drivers/gpu/drm/drm_fb_helper.c b/drivers/gpu/drm/drm_fb_helper.c > index 145d55f..730342c 100644 > --- a/drivers/gpu/drm/drm_fb_helper.c > +++ b/drivers/gpu/drm/drm_fb_helper.c > @@ -405,7 +405,7 @@ static int restore_fbdev_mode(struct drm_fb_helper *fb_helper) > > drm_warn_on_modeset_not_all_locked(dev);
