The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

Look, these are particularly pointless patches. The null setting is
only on teardown; the fact that we set something to NULL that should
already be null doesn't matter at all the extra cycles simply won't be
noticed. Please roll them into a single patch and send them to Jiří
Kosina and the trivial tree (cc'd) he'll take care of checking and
applying them (assuming they meet his criteria for worth bothering
with).
Thanks,
James

OK, I see.
I squashed all 20 patches into a single patch, and sent the single patch
to Jiri Kosina and the trivial tree, as you mentioned.
Thank you for your guidance.
