From 3b91e5507cddaca53bccf1524ff11a0ac5c85531 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Sun, 11 Feb 2007 20:43:19 +0100 Subject: mmc: Flush pending detects on host removal Make sure we kill of any pending detection runs when the host is removed instead of when it is freed. Also add some debugging to make sure the driver doesn't queue up more detection after it has removed the host.
