Subject[RFC PATCH 08/10] mmc: core: improve API to make clear hw_reset from bus_ops is for cards
Date
To make it unambiguous that bus_ops->hw_reset() is for cards and not for
controllers, we a) add 'card' to the function name and b) make the
function argument mmc_card instead of mmc_host. All users are converted,
too.
