From f38312c9b569322edf4baae467568206fe46d57b Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 23 Feb 2022 14:50:31 +0100 Subject: [PATCH] ACPI / x86: Add skip i2c clients quirk for Nextbook Ares 8 The Nextbook Ares 8 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 Signed-off-by: Rafael J.
