-Subject: [PATCH] Fix discarded const qualifiers
-
-It's unsafe to implicitly discard the const qualifier on a pointer. In
-overlay_fixup_phandle(), this was probably just an oversight, and making
-the "sep" variable a const char * is sufficient to fix it.
-
-In create_node(), however, the "p" variable is directly modifying the
-buffer pointed to by "const char* node_name". To fix this, we need to
-actually make a duplicate of the buffer and operate on that instead.
-
-This introduces a malloc()/free() and an unbounded strdup() into the
-operation, but fdtput isn't a long-running service and the node_name
-argument comes directly from argv, so this shouldn't introduce a
-significant performance impact.
