From 8b7feff881b7e9f065ddd718a6841121207c3c19 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Tue, 14 Nov 2006 22:13:13 +0100 Subject: [PATCH] mmc: correct request error handling We need to jump to the part of just flushing the request when we cannot claim the bus. Sending commands to a bus we do not own will give unpredictable results.
