Currently the I2C framework insists on devices supplying an I2C ID
table.  Many of the devices which do so unnecessarily adding quite a
few wasted lines to kernel code.  This patch allows drivers a means
to 'not' supply the aforementioned table and match on either DT
and/or ACPI match tables instead.

Sadly, it is not that easy...

That means we end up with drivers which cannot be used for run-time
instantiation via the 'new_device'-file in sysfs. I don't like that.

Would you mind explaining that a little please?  And perhaps point me
to the code?
