Subject: Re: [PATCH v1 5/5] driver core: Set fw_devlink=on by default
Hi Saravana, again ;)

This breaks (at least) probing of the PCIe controllers of my board. The
driver in question is
drivers/pci/controller/dwc/pci-layerscape.c
I've also put the maintainers of this driver on CC. Looks like it uses a
proper struct device. But it uses builtin_platform_driver_probe() and
apparently it waits for the iommu which uses module_platform_driver().
Dunno if that will work together.
The board device tree can be found here:
arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts
Attached is the log with enabled "probe deferral" messages enabled.
