	[PATCH] I2C updates: Document that the "id" member of the i2c_client structure was discarded in Linux 2.6.
	
	Original discussion:
	http://archives.andrew.net.au/lm-sensors/msg29038.html
	http://archives.andrew.net.au/lm-sensors/msg29041.html
	
	Bottom line:
	The "id" member of the i2c_client structure was discarded in Linux 2.6
	due to a lack of consistent use and overall need. While we of course
	won't backport this to Linux 2.4 so as to not break compatibility with
	existing 2.4 drivers, it still seems wise to update the documentation so
	that new drivers written for Linux 2.4 today (*sigh*) do not rely on it.
