Subject: platform/x86: Make dual_accel_detect() KIOX010A + KIOX020A detect more robust
From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit 085fc31f81765e061c78cdcab0e5516fd672bff7 upstream.
360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers
always have both a KIOX010A and a KIOX020A ACPI device (one for each
accel).
Theoretical some vendor may re-use some DSDT for a non-convertible
stripping out just the KIOX020A ACPI device from the DSDT. Check that
both ACPI devices are present to make the check more robust.
