Subject: [PATCH v2 0/4] device property: Add fwnode_get_name() helper

Hi,

This is the second version of my proposal for this helper. The
first version can be checked here:
https://lkml.org/lkml/2018/11/5/326

In order to support also ACPI properly, I decided to change the API.
The function fwnode_name() is now fwnode_get_name(), and instead of
returning pointer to the name, the function copies it to a buffer. I
did that because acpica does not offer a way to get a pointer to the
node name, and the name is clearly expected to be accessed only with
the namespace lock held.

I think this is better approach in any case. It will also solve the
problem of getting rid of the unit-address part from DT node names.

Let me know what you guys think.
