4.15-stable review patch. If anyone has any objections, please let me know.

From: Peter Rosin peda@axentia.se
commit b930151e5b55a0e62a3aad06876de891ac980471 upstream.
Without such a range, gpiolib fails with -EPROBE_DEFER, pending the addition of the range. So, without a range, gpiolib will keep deferring indefinitely.
