Subject: [PATCH v2 6/6] iommu/amd: Switch to use acpi_dev_hid_uid_match()
Date: Tue, 24 Sep 2019 22:37:39 +0300	[thread overview]
Message-ID: <20190924193739.86133-7-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20190924193739.86133-1-andriy.shevchenko@linux.intel.com>

Since we have a generic helper, drop custom implementation in the driver.
