Merge 4.10-rc7 into staging-next
This resolves the merge errors that were reported in linux-next and it picks up the staging and IIO fixes that we need/want in here as well. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

used by the device. I2C core will assign "irq" interrupt (or the very first
interrupt if not using interrupt names) as primary interrupt for the slave.
+Alternatively, devices supporting SMbus Host Notify, and connected to

Also, if device is marked as a wakeup source, I2C core will set up "wakeup"
interrupt for the device. If "wakeup" interrupt name is not present in the
binding, then primary interrupt will be used as wakeup interrupt.
