of: resolver: Add missing of_node_get and of_node_put In __of_find_node_by_full_name, add an of_node_get when detecting the desired element, to ensure that it ends up with a reference count that is one greater than on entering the function. Also in __of_find_node_by_full_name, add an of_node_put on breaking out of the for_each_child_of_node loop, to ensure that the reference count of the returned value is not double incremented. This change was made using Coccinelle. The semantic patch used for this is as follows: // <smpl> @@ expression e; local idexpression n; @@ for_each_child_of_node(..., n) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl Finally, add an of_node_put in for_each_child_of_node in the function __of_adjust_phandle_ref after the value returned by __of_find_node_by_full_name is no longer useful.

of: overlay: avoid race condition between applying multiple overlays The process of applying an overlay consists of: - unflatten an overlay FDT (flattened device tree) into an EDT (expanded device tree) - fixup the phandle values in the overlay EDT to fit in a range above the phandle values in the live device tree - create the overlay changeset to reflect the contents of the overlay EDT - apply the overlay changeset, to modify the live device tree, potentially changing the maximum phandle value in the live device tree There is currently no protection against two overlay applies concurrently determining what range of phandle values are in use in the live device tree, and subsequently changing that range. Add a mutex to prevent multiple overlay applies from occurring simultaneously. Move of_resolve_phandles() into of_overlay_apply() so that it does not have to be duplicated by each caller of of_overlay_apply(). The test in of_resolve_phandles() that the overlay tree is detached is temporarily disabled so that old style overlay unittests do not fail.
