drm: Add modeset object iterators
And roll them out across drm_* files. The point here isn't code prettification (it helps with that too) but that some of these lists aren't static any more. And having macros will gives us a convenient place to put locking checks into. I didn't add an iterator for props since that's only used by a list_for_each_entry_safe in the driver teardown code. Search&replace was done with the below cocci spatch. Note that there's a bunch more places that didn't match and which would need some manual changes, but I've intentially left these out for this mostly automated patch. iterator name drm_for_each_crtc; struct drm_crtc *crtc; struct drm_device *dev; expression head; @@ - list_for_each_entry(crtc, &dev->mode_config.crtc_list, head) { + drm_for_each_crtc (crtc, dev) { ... } @@ iterator name drm_for_each_encoder; struct drm_encoder *encoder; struct drm_device *dev; expression head; @@ - list_for_each_entry(encoder, &dev->mode_config.encoder_list, head) { + drm_for_each_encoder (encoder, dev) { ... } @@ iterator name drm_for_each_fb; struct drm_framebuffer *fb; struct drm_device *dev; expression head; @@ - list_for_each_entry(fb, &dev->mode_config.fb_list, head) { + drm_for_each_fb (fb, dev) { ... } @@ iterator name drm_for_each_connector; struct drm_connector *connector; struct drm_device *dev; expression head; @@ - list_for_each_entry(connector, &dev->mode_config.connector_list, head) { + drm_for_each_connector (connector, dev) { ... } Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
