Again, why would remove ever be NULL?

Yeah, I see.

But Greg, why does i2c-core do this?
like:drivers/i2c/i2c-core.c:

The i2c core has different requirements than the driver core does,
right?  They are two totally different things, please don't assume that
the rules for one are the same for the other.
