The rtc device node is always or at the very least can possibly be NULL.
Since v5.12-rc1-dontuse/3c9ea42802a1fbf7ef29660ff8c6e526c58114f6 this
will lead to a NULL pointer dereference.
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!
[1/1] rtc: pcf85063: fallback to parent of_node
commit: 03531606ef4cda25b629f500d1ffb6173b805c05
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.
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.
thanks,
