[PATCH] serial: amba-pl011: set fwnode from parent device

From: Emil Kronborg Andersen
Date: Fri Oct 13 2023 - 11:48:11 EST


After commit 3fb16866b51d ("driver core: fw_devlink: Make cycle
detection more robust"), consumer devices without their fwnode set
printed errors like the one below:

[ 0.261887] uart-pl011 3f201000.serial: Failed to create device link (0x180) with soc:firmware:gpio

To fix this, set the fwnode so fw_devlink can find and handle it
properly.

Fixes: 3fb16866b51d ("driver core: fw_devlink: Make cycle detection more robust")
