* If the host and card support UHS-I mode request the card
This (initially empty) table allows to match quirks early based on .compatible of the child node of some mmc/sdio interface. This allows to add quirks based on device tree instead of having card specific code in the host ops. A new macro SDIO_FIXUP_COMPATIBLE makes the definition readable. And we call mmc_fixup_device(sdio_card_init_methods) just after where host->ops->init_card() can be optionally called. Signed-off-by: H.
