i2c bus has 2 different types of device belonging to the same bus and
bus notifiers use device type to distinguish between adapters and clients.
Previously we only had i2c_adapter_type exported, which made code wanting
to work with i2c_client devices test for type not equal to adapter type.
This unfortunately is not safe if we ever add another type to the bus,
so let's export i2c_client_type as well.

Wolfram, this is the patch I was talking about in the other mail.

I see. From a glimpse, I am fine with the patch. I'll add Jean Delvare
to CC, though, in case I missed some detail he still knows. Furthermore,
while I agree that testing for "not adapter" when one means "is client"
is not nice, is there a bigger benefit than being correct in your queue?

No, just my dislike of testing for "dev->type != &i2c_adapter_type" in
the new i2c bus notifier when we want to work with i2c clients.

I might not answered your question ;) I use i2c_client_type export in
patch #6 of this series (I'll add you to CC in a moment), and I have
some other patches that should use it as well.

Thanks.
