Straightforward for all of them, no more leaks afterwards.

this one snippet is obsoleted by https://patchwork.ozlabs.org/patch/904326/

If 08/10 remains a deprecation, then it is sufficient to exclude the R-Car change,
otherwise I hope maintainers can deal with the proper ordering.

Isn't applying your patch:

https://patchwork.ozlabs.org/patch/904326/

and dropping the rcar hunk from this patch enough ?

absolutely, but it relies on any of two assumptions that
* my unmodified change is applied first, then Jan's adjusted change is applied,
* Jan's unmodified change is applied first, then my adjusted change is applied.

Otherwise there will be a trivial merge conflict, or even worse, if R-Car hunk
is removed as suggested, then of_pci_get_host_bridge_resources() is removed
instead of deprecation, and then my unmodified change is applied on top, it will
result in a window of commits, where R-Car PCIe driver won't be buildable, and
git-bisect users can be disappointed.

It makes little sense to include my change into Jan's series, thus I rely on
maintainers' awareness and smooth resolution of the issue by maintainers.

For what it's worth, I vote for of_pci_get_host_bridge_resources() removal.
