From 3e48138c2c66d8ff7d96c87a0535cd50078c742f Mon Sep 17 00:00:00 2001 From: Andrew Duggan Date: Tue, 2 Jun 2015 14:46:20 -0700 Subject: [PATCH] HID: i2c-hid: Do not set the ACPI companion field in the HID device The HID device does not need to know about the ACPI device associated with the underlying i2c device. Setting the ACPI companion field in the HID device also has the side effect of causing HID to be set as wake capable, since acpi_bind_one uses's the companion ACPI device's wakeup flags to set the device as wake capable. Which results in power/wakeup files in sysfs for the HID device which do not do anything.
