commit 68b356eb upstream. Currently the ad7266 driver treats any failure to get vref as though the regulator were not present but this means that if probe deferral is triggered the driver will act as though the regulator were not present. Instead only use the internal reference if we explicitly got -ENODEV which is what is returned for absent regulators.
