Input: soc_button_array - silence -ENOENT error on Dell XPS13 9365
The Dell XPS13 9365 has an INT33D2 ACPI node with no GPIOs, causing
the following error in dmesg:
[ 7.172275] soc_button_array: probe of INT33D2:00 failed with error -2
This commit silences this, by returning -ENODEV when there are no GPIOs.
