From 411e689d929d5fc2e9066e30de55e8bcdbd573ad Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 14 Apr 2011 22:32:00 +0000 Subject: [PATCH] powerpc/nvram: Search for nvram using compatible As well as searching for nodes with type = "nvram", search for nodes that have compatible = "nvram". This can't be converted into a single call to of_find_compatible_node() with a non-NULL type, because that searches for a node that has _both_ type & compatible = "nvram".
