i2c: Convert most new-style drivers to use module aliasing
Jean Delvare [Tue, 29 Apr 2008 21:11:40 +0000 (23:11 +0200)]
Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.
