Subject: [PATCH] libfdt: fdt_path_offset_namelen: Reject empty paths
|
|
|
|
Make empty paths result in FDT_ERR_BADPATH.
|
|
|
|
Per the specification (v0.4-rc4):
|
|
|
|
> The convention for specifying a device path is:
|
|
> /node-name-1/node-name-2/node-name-N
|
|
>
|
|
> The path to the root node is /.
|
|
>
|
|
> A unit address may be omitted if the full path to the
|
|
> node is unambiguous.
|
