From dbc40a0e582a88d2561d13d1fea4f3496bff9650 Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Tue, 22 Apr 2008 14:45:39 -0300 Subject: V4L/DVB (7303): pvrusb2: Ensure that default input selection is actually valid Previously the pvrusb2 driver just started with the default input to be "television". But if the device doesn't support an analog tuner then this default must be different. New logic here selects a reasonable default based on the actual valid set of available inputs.
