From fd6e9d3945ee122eb513ada8b17296d243c1ce5e Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Sat, 12 May 2007 03:19:38 +1000 Subject: [PATCH] [POWERPC] Don't complain if size-cells == 0 in prom_parse() An mdio bus scan was added with ucc_geth phylib migration patches, now machines complain on boot, saying: prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@00 prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@01 since size-cells can indeed be 0, this patch fixes the check.
