Subject: [PATCH v1 6/8] platform/x86: surface3_wmi: Switch DMI table match to a test of variable
Date:   Fri, 17 Jan 2020 19:56:24 +0200
Message-Id: <20200117175626.56358-6-andriy.shevchenko@linux.intel.com>
In-Reply-To: <20200117175626.56358-1-andriy.shevchenko@linux.intel.com>

Precedence: bulk

Since we have a common x86 quirk that provides an exported variable,
use it instead of local DMI table match.
