Have you tried "<vendor>, 24c64"? All I can say is that it works for me. =

issue you are facing. This patch is just about extending the support.

According to of_modalias_node, the prefix is stripped anyway, so that
wouldn't help.
The code probably worked using the buggy probing...

the module name and the device id to be different.
This makes the at24 driver no longer rely on probing (which it claims
is buggy anyway) and also benefits other drivers that support multiple
devices, but where probing is difficult (e.g. lm90 driver).

I'm in the process of getting employer approval to get these patches
upstream.

It'll get approved ;) It's the first time I'm taking these steps, but
the procedures
are there, so at most it'll take some extra time.

I hope you will get it approved, it is a lot easier to talk about code :)
