Subjectlinux-next: build failure after merge of the staging tree
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).
