Subject: [PATCH v1 1/3] eeprom: idt_89hpesx: Put fwnode in matching case during ->probe()

device_get_next_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.

Fixes: db15d73e5f0e ("eeprom: idt_89hpesx: Support both ACPI and OF probing")
