You should really mention this in the commit log, maybe something like:


[PATCH] drivers/of: Constify device_node->name and ->path_component_name

Neither of these should ever be changed once set. Make them const

Also use kstrdup() instead of memcpy() so we don't attempt to modify them.

Build tested with defconfigs on ARM, PowerPC, Sparc, MIPS, x86 among
others.


Thanks,
