I don't disagree. The rationale for the change is that I simply reverted
to how the code was before 33cf00e5, assuming that the introduction of
spi as a local variable was caused by it being used more than once. If
you believe this was a good change on its own and would prefer to keep
it that way, I could send a patch replacing this one and only changing
&spi->dev to dev. Let me know.

And yes, this is not the most groundbreaking patch either way,
granted ;-)
