Subject: [PATCH resend] DVB: firedtv: FireDTV S2 problems with tuning solved

This came in via linux1394-devel.  If there are no objections, I'll
include it in my pull request to Linus which I want to send in a few
hours.  It's also good to send to stable.

Signed-off-by: Beat Michel Liechti <bml303@...il.com>

Tuning was broken on FireDTV S2 (and presumably  FloppyDTV S2) because a
wrong opcode was sent.  The box only gave "not implemented" responses.
Changing the opcode to _TUNE_QPSK2 fixes this for good.
