Subject: [PATCH v1] usb: core: Add ACPI support for USB interfaces
Date: Mon, 23 Mar 2020 21:55:43 +0200 [thread overview]
Message-ID: <20200323195543.51050-1-andriy.shevchenko@linux.intel.com> (raw)
The ACPI companion of the device has to be set for USB interfaces
in order to read and attach the properties described in the ACPI table.
Use ACPI_COMPANION_SET macro to set this.
