[PATCH 5.17 0860/1126] ACPI / x86: Add skip i2c clients quirk for Lenovo Yoga Tablet 1050F/L

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 4fecb1e93e4914fc0bc1fb467ca79741f9f94abb ]

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.
