[ 13/47] media: dvb_frontend: fix a regression with DVB-S zig-zag

From: Greg KH
Date: Fri May 18 2012 - 19:17:45 EST


3.3-stable review patch. If anyone has any objections, please let me know.

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

From: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx>

commit 910a5f2e9642d5be373beae3d29e1c4a3bc7d83b upstream.

Changeset 5bfaadde broke zig-zag for DVB-S drivers that don't
implement get_tune_settings() callback.

Fix the code, in order to allow it to work as before, otherwise
some channels may not be tuned anymore.

Fix Fedora Bugzilla:
