The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.

This is a basic driver for the Zeitec ZET6223 I2C touchscreen
controllers. The driver does not support firmware loading, which is not
required for all tablets which contain this chip.
