[patch 050/101] DVB: digitv: open nxt6000 i2c_gate for TDED4 tuner handling

[Greg KH]

From: Michael Krufky <mkrufky@xxxxxxxxxxx>

dvb-pll normally opens the i2c gate before attempting to communicate with
the pll, but the code for this device is not using dvb-pll.  This should
be cleaned up in the future, but for now, just open the i2c gate at the
appropriate place in order to fix this driver bug.

(cherry picked from commit 2fe22dcdc79b8dd34e61a3f1231caffd6180a626)
