From 964f9ce2ff42dc47cf40fbd2f5c81cd60689e384 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Fri, 20 Jul 2007 18:20:36 +0200 Subject: [PATCH] sdhci: make sure to clear the error interrupt The controller has a bit indicating that one of the higher bits (the error bits) are set. A previous bug caused this bit to be masked, but since that bug has been fixed we have to clear it explicictly.
