Subject: [PATCH 10/12] ASoC: Intel: avs-rt298: remove redundant dapm routes
Date:   Mon, 12 Jun 2023 19:09:56 +0800
Message-Id: <20230612110958.592674-11-brent.lu@intel.com>
In-Reply-To: <20230612110958.592674-1-brent.lu@intel.com>
References: <20230612110958.592674-1-brent.lu@intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Two routes "AIF1 Playback<-sspX Tx" and "sspX Rx<-AIF1 Capture" are
created by snd_soc_dapm_connect_dai_link_widgets() automatically.
Remove the duplicate routes.
