Andy Shevchenko bff1c3b39a device property: fix potential NULL pointer dereference 
commit ecc87eed7b upstream.

In device_add_property_set() we check pset parameter for a NULL, but few lines
later we do a pointer arithmetic without check that will crash kernel in the
set_secondary_fwnode().

Here we check if pset parameter is NULL and return immediately.

Fixes: 16ba08d5c9 (device property: Introduce firmware node type for platform data)
