arm psci_probe() bug

[Alexander Shiyan]

Hello.

I found a bug in psci processing.
Currently the kernel writes the following on boot:
psci: probing for conduit method from DT.
psci: invalid "method" property:
...

In the psci_probe() function we do the following:
ret = of_property_read_string(dev->of_node, "method", &method);
and use this (method) variable as an argument for of_psci_fixup().
I suspect we are free this variable at of_property_write_string ->
of_set_property > of_delete_property.

Can you confirm my thought and correct it in the right direction?

Thanks!
