From 547bf60a782e5d6397e4ed6c001bd1ae0633d8f0 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 24 Feb 2007 00:55:14 +0100 Subject: Improve chip matching in v4l2_register for VIDIOC_DBG_G/S_REGISTER From: Hans Verkuil The chip matching in struct v4l2_register was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to differentiate between two i2c chips driven by the same driver on one board (e.g. a PVR500 with two tuner chips, one for analog TV and one for radio). It has now been improved making it much more powerful.
