i2c: Legacy i2c drivers shouldn't issue uevents
Prevent legacy drivers from issuing uevents for device creation/removal, so that userspace can't cause modprobing loops for them. This became a problem for some legacy PC drivers. I can't easily see it becoming an issue with I2C legacy drivers, but consistency-in-paranoia seems likely to be a good thing here. For usable i2c-level driver model uevents, just switch to a new-style driver. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
