From 526b5b3ed97bac22ed0c9feed97adcdc3a25244c Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 15 Oct 2009 10:58:02 -0600 Subject: of: merge of_node_get(), of_node_put() and of_find_all_nodes() Merge common code between Sparc, PowerPC and Microblaze. Sparc differs in the implementation at this point, so this patch uses a #ifdef to handle sparc differently for now. The merging of implementations will occur in a later patch Signed-off-by: Grant Likely Acked-by: David S.
