Subject: [PATCH] serial: amba-pl011: set fwnode from parent device
Date: Fri, 13 Oct 2023 17:47:42 +0200 [thread overview]
Message-ID: <20231013154742.76836-1-emkan@prevas.dk> (raw)
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")
