dsa: fix 88e6xxx statistics counter snapshotting
Stephane Contri [Thu, 2 Jul 2009 23:26:48 +0000 (23:26 +0000)]
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.
