From c7d29e2f530654aa0c323aafb94d42a6a718482c Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 18 Jan 2009 19:37:59 -0300 Subject: V4L/DVB (10249): v4l2-common: added v4l2_i2c_tuner_addrs() Add v4l2_i2c_tuner_addrs() to obtain the various I2C tuner addresses. This will be used in several drivers, so make this a common function as we do not want to have these I2C addresses all over the place.
