linux/drivers/ps3/ps3av.c
Geert Uytterhoeven ef596c697a [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.
