an allyesconfig bootup generates the driver core warning below, in
alsa_card_dummy_init().

This is i386 or x86_64? This one, and the others, your been sending look
like initcall ordering issues. For instance, some alsa init usually runs
after alsa_card_dummy_init() , but in your kernel alsa_card_dummy_init()
runs first. It's a problem even in the same initcall level.
