platform/x86: ideapad-laptop: Ignore VPC event bit 10
VPC event bit 10 gets set on a Yoga 300-11IBR when the EC believes that the device has changed between laptop/tent/stand/tablet mode. The EC relies on getting angle info from 2 accelerometers through a special windows service calling a DSM on the DUAL250E ACPI-device. Linux does not do this, making the laptop/tent/stand/tablet mode info unreliable. Ignore VPC event bit 10 to avoid the warnings triggered by the default case in ideapad_acpi_notify(). Note that the plan for Linux is to have iio-sensor-proxy read the 2 accelerometers and have it provide info about which mode 360° hinges 2-in-1s to the rest of userspace: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/issues/216 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20210523172331.177834-1-hdegoede@redhat.com
