+of I2C adapters. Each specific adapter driver either depends on one algorithm
+driver, or includes its own implementation.
 
 A Driver driver (yes, this sounds ridiculous, sorry) contains the general
 code to access some type of device. Each detected device gets its own
 data in the Client structure. Usually, Driver and Client are more closely
 integrated than Algorithm and Adapter.

 At this time, Linux only operates I2C (or SMBus) in master mode; you can't
 use these APIs to make a Linux system behave as a slave/device, either to
 speak a custom protocol or to emulate some other device.
