[PATCH] MMC: core/core.c: fixed: delayed_work was never cancelled

From: Jorg Schummer
Date: Tue Feb 17 2009 - 08:44:18 EST


The delayed work item mmc_host.detect is now cancelled before flushing
the work queue. This takes care of cases when delayed_work was scheduled
for mmc_host.detect, but not yet placed in the work queue.
