Subject: [PATCH v4 8/9] ASoC: rt5645: Switch DMI table match to a test of variable
Date:   Wed, 15 Apr 2020 17:55:23 +0300
Message-Id: <20200415145524.31745-9-andriy.shevchenko@linux.intel.com>
In-Reply-To: <20200415145524.31745-1-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.

Note, arch/x86/kernel/quirks.c::early_platform_detect_quirk() prints
the detected platform.
