From 076c3454d645ac937bfc293235e3a31e31794114 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 29 May 2013 06:59:36 -0300 Subject: [PATCH] [media] cx18: remove g_chip_ident support The av-core is really a subdev, so there is no need anymore to act as if it is a 'second' bridge chip. As a result of this the g_chip_ident implementation can be completely dropped.
