Ok, I see.

One more question: how can I specify "ti,wl1251" in some struct mmc_fixup table?
Does it need another macro like MMC_FIXUP() or SDIO_FIXUP() to set the .name
field?

Because I want to get rid of init_card. It is host specific and not client
specific.

Ok. Would be some add_wl1251_quirk() then.

BR and thanks,
