+Subject: [PATCH] Revert "egl/wayland: deprecate drm_handle_format() and
+ drm_handle_capabilities()"
+
+Commit af1ee8e010441f8f2ed8c77065b159652a4ac9fe dropped support to
+wl_drm, as we thought that most compositors from active projects were
+already supporting zwp_linux_dmabuf_v1.
+
+But that's not true, so revert this commit in order to give these
+projects a longer transition period.
+
+Note that we didn't add back the support to GEM name API, and that was
+on purpose.
