From ef596c697a4d80048eccf50530153d7e3330c127 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sat, 10 Mar 2007 00:05:38 +0100 Subject: [POWERPC] ps3: always make sure were running on a PS3 Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that we are actually running on a PS3 (pointed out by Arnd). Correct existing checks in other subsystems/drivers to return -ENODEV instead of zero.
