From db@blackbox.site Wed Jun 29 08:17:44 2005 Date: Wed, 29 Jun 2005 07:14:06 -0700 From: david-b@pacbell.net To: Subject: I2C: minor I2C doc cleanups Message-Id: <20050629141406.1947DC894D@blackbox.site> The I2C stack has long had "id" fields, of rather dubious utility, in many data structures. This removes mention of one of them from the documentation about how to write an I2C driver, so that only drivers that really need to use them (probably old/legacy code) will have any reason to use this field.

This means that your driver will be notified when new adapters are found. This is almost always what you want.
