From 32f18e596141f40dbc5d8700b2730371ffd3055f Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 8 Apr 2022 10:00:44 +0200 Subject: mmc: improve API to make clear hw_reset callback is for cards To make it unambiguous that the hw_reset callback is for cards and not for controllers, we add 'card' to the callback name and convert all users in one go. We keep the argument as mmc_host, though, because the callback is used very early when mmc_card is not yet populated.
