This breaks at least an arm multi_v7_defconfig build:
/build/stage/linux/sound/soc/soc-core.c: In function ‘snd_soc_bind_card’:
/build/stage/linux/sound/soc/soc-core.c:2055:36: error: ‘struct snd_soc_card’ ha

This should be a separate change, and DMI is a term specific to the
ACPI/EFI so I don't think we should be using it as a generic here, this
seems like a step back. If we want to make a change there I'd expect it
to be more picking the actual card driver name.
