The driver field in the struct snd_ctl_card_info is a valid user space identifier. Actually, many ASoC drivers do not care and let to initialize this field using a standard wrapping method.
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 s no member named ‘dmi_longname’ 2055 | if (card->long_name == card->dmi_longname) | ^~
Also, it does not make sense to set the driver field to the card name composed from DMI. This card name is longer in most (all?) cases. Use a generic "ASoC-DMI" string here.
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.
