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@xxxxxxxxxx> --- drivers/platform/x86/ideapad-laptop.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/drivers/platform/x86/ideapad-laptop.c b/drivers/platform/x86/ideapad-laptop.c index 387817290921..784326bd72f0 100644 --- a/drivers/platform/x86/ideapad-laptop.c +++ b/drivers/platform/x86/ideapad-laptop.c @@ -1408,6 +1408,18 @@ static void ideapad_acpi_notify(acpi_handle handle, u32 event, void *data) case 6: ideapad_input_report(priv, bit); break; + case 10: + /* + * This event gets send on a Yoga 300-11IBR when the EC + * believes that the device has changed between laptop/ + * tent/stand/tablet mode.
