From 509b7455ef87e1447670c51037cabbf93d772d6f Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 22 Oct 2012 11:32:30 +1100 Subject: of/fdt: Don't copy garbage after "/" in root node path The root node path must be internally converted to "/", or various pieces of code looking for it that way will fail. The code to do that however had a bug where we might incorrectly append pieces of the original path from the fdt to the "/". We should probably add a proper dedicated accessor for the root node but in the meantime this patch should fix it.
