From 48972d907a28de17c2a5108a3ee3d5f3eb434376 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 2 Jan 2012 01:15:37 +0000 Subject: mmc: Implement card detection. Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.
