ACPI / x86: Add skip i2c clients quirk for Lenovo Yoga Tablet 1050F/L
The Yoga Tablet 1050F/L is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts (the Android x86 kernel fork ignores I2C devices described in the DSDT). Add a ACPI_QUIRK_SKIP_I2C_CLIENTS for the Nextbook Ares 8 to the acpi_quirk_skip_dmi_ids table to woraround this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
