Hi All, Here is a patch series fixing an oops when there is no ACPI fwnode associated with a PCI enumerated LPSS I2C controller: https://bugzilla.redhat.com/show_bug.cgi?id=1687065 This is fixed by the first patch in this series, which modifies i2c-designware-platdrv.c to fix this. The fix is enabled conditionally because otherwise it might break things on platforms where i2c-designware controllers are enumerated through e.g. devicetree. The second patch modifies intel-lpss-pci.c to pass the new "linux,use-dynamic-adapter-nr" devicetree property to activate the fix. The first patch should be merged first, so that the devicetree prop name is "stable", then the second patch can be merged independently through the mfd tree. Regards, Hans
