    ACPI: x86: Add skip i2c clients quirk for Lenovo Yoga Book X90 · 1a1e7540
    Hans de Goede authored
    The Lenovo Yoga Book X90 is a x86 tablet which ships with Android x86
    as factory OS. The Android x86 kernel fork ignores I2C devices described
    in the DSDT, except for the PMIC and Audio codecs.
    
    As usual the Lenovo Yoga Book X90's DSDT contains a bunch of extra I2C
    devices which are not actually there, causing various resource conflicts.
    Add an ACPI_QUIRK_SKIP_I2C_CLIENTS quirk for the Lenovo Yoga Book X90
    to the acpi_quirk_skip_dmi_ids table to woraround this.
    
    The DSDT also contains broken ACPI GPIO event handlers, disable those too.
