From 10e43d90da572f088f15cadfb5cc83cd762041c3 Mon Sep 17 00:00:00 2001 From: Kusanagi Kouichi Date: Fri, 22 Jan 2010 04:54:46 -0300 Subject: [PATCH] V4L/DVB: cx25840: Fix composite detection If CX25840_VIN1_CH1 and the like is used, input is not detected as composite. Their value is 0x800000XX and CX25840_COMPONENT_ON is 0x80000200. So 739 else if ((vid_input & CX25840_COMPONENT_ON) == 0) this condition never be true.
