From 75ba899e95217fe9002878edc2777bdd49d908c3 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Mon, 19 Aug 2013 14:01:17 +0300 Subject: HID: i2c-hid: use correct type for ACPI _DSM parameter ACPI 5.0 specification requires the fourth parameter to the _DSM (Device Specific Method) to be of type package instead of integer. Failing to do that we get following warning on the console: ACPI Warning: \_SB_.PCI0.I2C1.TPL0._DSM: Argument #4 type mismatch - Found [Integer], ACPI requires [Package] (20130517/nsarguments-95) Fix this by passing an empty package to the _DSM method. The HID over I2C specification doesn't require any specific values to be passed with this parameter.
