From dd6c4b9807581b37bf68ba3cd160c6859f070d39 Mon Sep 17 00:00:00 2001 From: Will Newton Date: Thu, 10 Feb 2011 14:37:03 -0500 Subject: [PATCH] mmc: dw_mmc: Run card detect tasklet during slot initialisation. We need to run the card detect tasklet at the end of slot initialisation as it is possible that a card has been inserted prior to boot, so we don't see an insertion interrupt and now the card is sitting there inserted but with no power to it.
