From a0a7ae8939e3fdecf5478ddba54562e23de7ca1d Mon Sep 17 00:00:00 2001 From: Andre Detsch Date: Wed, 5 Dec 2007 13:49:31 +1100 Subject: [POWERPC] cell: safer of_has_vicinity routine This patch changes the way we check for the existence of vicinity property in spe device nodes. The new implementation does not depend on having an initialized cbe_spu_info[0].spus, and checks for presence of vicinity in all nodes, not only in the first one.
