From 660acd54d1656f6361819d8d6b377a2aa2438748 Mon Sep 17 00:00:00 2001 From: Matthias Schwarzott Date: Thu, 2 Oct 2014 02:21:04 -0300 Subject: [PATCH] [media] cx231xx: drop unconditional port3 switching All switching should be done by i2c mux adapters. Drop explicit dont_use_port_3 flag. Drop info message about switch. Only the removed code in start_streaming is questionable: It did switch the port_3 flag without accessing i2c in between.
