overlay_update_local_node_references() saves the result of
fdt_subnode_offset() into variable tree_child but checks for variable
ret afterwards. As this does not make sense, check tree_child instead of
ret.
This bug has been found by compiling with clang. The compiler reported
the following warning:
libfdt/fdt_overlay.c:275:7: error: variable 'ret' may be
uninitialized when used here
[-Werror,-Wconditional-uninitialized]
if (ret == -FDT_ERR_NOTFOUND)
^~~
libfdt/fdt_overlay.c:210:9: note: initialize the variable 'ret' to
silence this
warning
int ret;
^
= 0
