Subject: dvb-sat: fix rangeswitch logic Author: Mauro Carvalho Chehab <mche...@osg.samsung.com> Date: Mon Feb 13 07:33:21 2017 -0200 There are two bugs at the rangeswitch logic: 1) the logic there that checks if the frequency doesn't match may cause it to go past array; 2) rangeswitch == 0 means that there's no range switch for that LO. On such case, it should not increment the LO index.
