+
+This reverts commit 1fae6eb0fc91d3ecb539e03f9e4dcd1c53ada553.
+
+Upstream commit was a fix for an overlook of setting "ent.is_valid"
+twice after 5d65b64a3d97 ("net: dsa: b53: Add support for MDB").
+
+Since MDB support was not backported to stable kernels (it's not a bug
+fix) there is nothing to fix there. Backporting this commit resulted in
+"env.is_valid" not being set at all.
