[PATCH] i2c #3/3: add class field to i2c_adapter
This is the last of three patches for i2c. It introduces a new field
to i2c_adapter which classifies the kind of hardware a i2c adapter
belongs to (analog tv card / dvb card / smbus / gfx card ...). i2c chip
drivers can use this infomation to decide whenever they want to look for
hardware on that adapter or not. It doesn't make sense to probe for a
tv tuner on a smbus for example ...
