Subject: [PATCH 2/8] ASoC: SOF: Intel: simplify logic for DMI_L1 handling
Date: Thu, 10 Jun 2021 15:53:20 -0500	[thread overview]
Message-ID: <20210610205326.1176400-3-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20210610205326.1176400-1-pierre-louis.bossart@linux.intel.com>

We don't need to test in multiple places if the kconfig
SND_SOC_SOF_HDA_ALWAYS_ENABLE_DMI_L1 is enabled or not, we might as
well set the existing DMI_L1_COMPATIBLE flag.
