We exactly threw this out of at24 in the new revision, as name-matching
stored quite some data in the driver which was needed only once during
initialization. Also, it was not very flexible; what if you want to mark
this chip as read-only, your variant has bigger page size and could be
faster... The list of device names would grow too fast IMHO, adding a
new feature which is selectable by a flag could easily double it.
Then again: If Jochen's patches get applied, then I have to use
MODULE_DEVICE_TABLE anyhow, or?
