[PATCH] Firmware class name collision

[Markus Rechberger]

Hi,

following patch fixes the i2c name collision with i2c-dev.

http://mcentral.de/wiki/index.php/Bugtracker#i2c_core_problem

This issue has been experienced with em28xx and saa7133 based devices.
I discussed that problem with Jean Delvare a while ago and he proposed 
to add a prefix to the class name.
