-Subject: [PATCH] of: overlay: Correct symbol path fixups
-
-When symbols from overlays are added to the live tree their paths must
-be rebased. The translated symbol is normally the result of joining
-the fragment-relative path (with a leading "/") to the target path
-(either copied directly from the "target-path" property or resolved
-from the phandle). This translation fails when the target is the root
-node (a common case for Raspberry Pi overlays) because the resulting
-path starts with a double slash. For example, if target-path is "/" and
-the fragment adds a node called "newnode", the label associated with
-that node will be assigned the path "//newnode", which can't be found
-in the tree.
-
-Fix the failure case by explicitly replacing a target path of "/" with
-an empty string.
-
-Fixes: d1651b03c2df ("of: overlay: add overlay symbols to live device tree")
