[PATCH] I2C: use chip driver name to request regions

> Trivial patch against 2.6.10-rc3-bk2.
> When request_region is called name is set to "", use module name.

Correct. I even think we should do the same for other chip drivers. For
now they all use an arbitrary string. Using the driver's name would be
both more consistent and more efficient (spares some bytes of memory).
