Rather than compare the format u32s of two format infos, we can direclty compare the format info pointers themselves. Noramlly all the ->format pointers all point to somwehere in the big array, so this is a valid way to test for equality. Also drivers may want to point ->format at a private format info struct instead (eg. for special compressed formats with extra planes), so just comparing the pixel format values wouldn't necessaritly even work. But comparing the pointers will also take care of that case. @@ struct drm_framebuffer *a; struct drm_framebuffer *b; @@ ( - a->format->format != b->format->format + a->format != b->format | - a->format->format == b->format->format + a->format == b->format ) @@ struct drm_plane_state *a; struct drm_plane_state *b; @@ ( - a->fb->format->format != b->fb->format->format + a->fb->format != b->fb->format | - a->fb->format->format == b->fb->format->format + a->fb->format == b->fb->format ) @@ struct drm_crtc *crtc; struct drm_framebuffer *x; @@ ( - crtc->primary->fb->format->format != x->format->format + crtc->primary->fb->format != x->format | - x->format->format != crtc->primary->fb->format->format + x->format != crtc->primary->fb->format ) @@ struct drm_mode_set *set; @@ - set->fb->format->format != set->crtc->primary->fb->format->format + set->fb->format != set->crtc->primary->fb->format Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Suggested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1479498793-31021-35-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> |
