Unfortunately while this may fix the particular use-case on STM32, it
breaks all other users as the 'gpio-line-names' property doesn't live
on dev_fwnode(&gdev->dev) but on dev_fwnode(chip->parent).

How about we first look for this property on the latter and only if
it's not present descend down to the former fwnode?

Oops, I have tested on x86 and it worked the same way.

Lemme check this, but I think the issue rather in ordering when we apply fwnode
to the newly created device and when we actually retrieve gpio-line-names
property.

Hmm... I can't see how it's possible can be. Can you provide a platform name
and pointers to the DTS that has been broken by the change?
