From 179fd15a99175e8e22516edbb1894c3348842f3a Mon Sep 17 00:00:00 2001 From: Oliver Endriss Date: Mon, 10 Jan 2011 06:36:22 -0300 Subject: [PATCH] [media] stv090x: Fix losing lock in dual DVB-S2 mode Do not clear registers ACLC/BCLC in DVB-S2 mode for Cut <= 20. Otherwise, the demod could lose the lock periodically. Verified with cineS2 and Duoflex.
