Shouldn't you also select the MFD part of WM8994 here ?

Could we have a less cryptic name here, e.g. "HiFi Primary" ?

I'd say this whole np test could be dropped, we will fail right below at the snd_soc_of_parse_card_name() function call if np is NULL. Such a situation seems highly unlikely anyway.

I guess it would fit in a single line.

You can drop this .owner field assignment, it's also done in module_platform_driver() macro.
