Function fdt_set_name 

pub unsafe extern "C" fn fdt_set_name(
    fdt: *mut c_void,
    nodeoffset: c_int,
    name: *const c_char,
) -> c_int

fdt_set_name - change the name of a given node @fdt: pointer to the device tree blob @nodeoffset: structure block offset of a node @name: name to give the node

fdt_set_name() replaces the name (including unit address, if any) of the given node with the given string. NOTE: this function can’t efficiently check if the new name is unique amongst the given node’s siblings; results are undefined if this function is invoked with a name equal to one of the given node’s siblings.

This function may insert or delete data from the blob, and will therefore change the offsets of some existing nodes.

returns: 0, on success -FDT_ERR_NOSPACE, there is insufficient free space in the blob to contain the new name -FDT_ERR_BADOFFSET, nodeoffset did not point to FDT_BEGIN_NODE tag -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, standard meanings
