From 39342dbb27323f174b286c9e19b9687d492b2d1a Mon Sep 17 00:00:00 2001 From: Lutz Sammer Date: Fri, 7 Oct 2011 16:11:37 -0300 Subject: [media] stb0899: Fix slow and not locking DVB-S transponder(s) In stb0899_status stb0899_check_data the first read of STB0899_VSTATUS could read old (from previous search) LOOP status bit and the search fails on a good frequency. With the patch more transponder could be locked and locks about 2* faster.
