Jonathan Cameron	db8fa7311d	iio:adc:vf610 ensure correct handing of interruption of wait for completion ... Issue highlighted by smatch warning: CHECK drivers/iio/adc/vf610_adc.c drivers/iio/adc/vf610_adc.c:466 vf610_read_raw() warn: unsigned 'ret' is never less than zero. As wait_for_completion_interruptible_timeout can return -ERESTARTSTSYS, if interrupted, ret must be signed.
