To fix this we fallback to using the parent node which is the i2c client node as set by devm_rtc_allocate_device().

Applied, thanks!

I made the fallback unconditionnal because this should have been that way from the beginning as you point out.
can you queue this for stable, as it causes a NULL Pointer deref with (at least) v5.12.
Thanks, Marc

After it hits Linus's tree, let stable@vger.kernel.org know the id and we will glad to add it to the stable trees.

It's in Linus's tree since v5.13-rc1~64^2~19 and the commit id is 03531606ef4c ("rtc: pcf85063: fallback to parent of_node").
