Subject: [PATCH] dsa: fix 88e6xxx statistics counter snapshotting
Date: Friday, July 3, 2009 - 5:26 am

From: Stephane Contri <Stephane.Contri@grassvalley.com>

The bit that tells us whether a statistics counter snapshot operation
has completed is located in the GLOBAL register block, not in the
GLOBAL2 register block, so fix up mv88e6xxx_stats_wait() to poll the
right register address.
