From c3bf1b32148a59bc0a8e58c126d642236c7febc1 Mon Sep 17 00:00:00 2001 From: Andrew de Quincey Date: Mon, 10 Apr 2006 09:27:37 -0300 Subject: Add sysfs device links to dvb devices From: Andrew de Quincey Currently in /sys/class/dvb/dvbX.demuxY/ we have: dev uevent With the patch, we have (for a PCI DVB device): dev device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:03:0d.0 uevent So userspace tools can (finally) work out which physical device a DVB adapter refers to. Previously you had to kinda look through dmesg and hope that it hadn't been dumped out of the buffer. This makes debugging a lot easier if the system has been up for a long time! This is done by adding an extra 'struct device *' parameter to dvb_register_adapter(). It will work with any kind of standard linux 'device'. Additionally, if someone has an embedded system which does things differently, they can simply supply 'NULL' and the behaviour will be as before - the link will simply not appear.
