I already applied the series. Looking forward to the next steps ;-).

Sorry if I've been harsh to you when saying that your contributions
were 'useless'. It's just that we regularly receive random 'cleanups'
(generated with coccinelle, or similar tools), and, while these kind of
things help getting consistent code across the kernel, or
simplifying/clarifying existing code, it's not the kind of rework that
really improve the framework or address drivers flaws.

It's also sometime used by developers who just want to have patches in
mainline, and never reach the next step (contribute things to really
improve a framework or add support for new features/hardware).
Another reason I'm reluctant to apply such cleanup changes is that,
sometime a simple change might actually break things (see the 'mtd:
nand: denali_pci: add missing pci_release_regions() calls' patch).

And the last aspect is that cosmetic changes pollutes other
contributions by delaying their review.

Don't mistake me, if all these cleanups are serving a higher purpose (in
your case, adding support for a new IP revision in a clean way), then
that's all fine. But otherwise, I tend to dequeue those patches last.

Regards,

Boris
