[PATCH 4.19 197/421] eeprom: idt_89hpesx: Put fwnode in matching case during ->probe()

[Greg Kroah-Hartman]

From: Andy Shevchenko <andy.shevchenko@xxxxxxxxx>

[ Upstream commit 3f6ee1c095156a74ab2df605af13020f1ce3e600 ]

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")
