This patch landed some time ago in linux-next as commit 4104ca776ba3
("of: property: Add fw_devlink support for interrupts"). It breaks MMC
host controller operation on ARM Juno R1 board (the mmci@50000 device
defined in arch/arm64/boot/dts/arm/juno-motherboard.dtsi). I didn't
check further what's wrong there as without MMC mounting rootfs fails in
my test system.
