------------------

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

commit 1ded3f59f35a2642852b3e2a1c0fa8a97777e9af upstream.

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.
