Subject: [PATCH] Input: soc_button_array - Silence -ENOENT error on Dell XPS13 9365
Date: Sun, 20 Aug 2017 11:42:21 +0200 [thread overview]
Message-ID: <20170820094221.7629-1-hdegoede@redhat.com> (raw)
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.
