Devices without internal display like Mac mini, Studio and Pro do not have an ambient light sensor. The ioreg subprocess will not produce any output but return with exit status 0. Handle this gracefully. This might hide unexpected cases on devices with ALS but a simple solution without listing devices. Fixes: 766ecc0 ("Extract and store ALS calibration") Signed-off-by: Janne Grunau <j@jannau.net>
