powerpc: 8xx: get cpu node with of_get_cpu_node (38959a09) · Commits · 戴 / test

"device_type" use is deprecated for FDT though it has continued to be used for nodes like cpu nodes. Use of_get_cpu_node() instead which works using node names by default. This will allow the eventually removal of cpu device_type properties. Also, fix a leaked reference and add a missing of_node_put.
