Hi Greg, After merging the staging tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/hid/hid-sensor-hub.c: In function 'sensor_hub_probe': drivers/hid/hid-sensor-hub.c:599:3: error: too few arguments to function 'mfd_add_devices' Caused by commit 401ca24fb34a ("HID: sensors: introduce sensor framework") interacting with commit 6607bad3d763 ("mfd: core: Push irqdomain mapping out into devices") from the mfd tree. I have added the following merge fix patch and can carry it as necessary (no action is required).
