Subject: ASoC: dapm: use component prefix when checking widget names
From: Shuming Fan <shumingf@xxxxxxxxxxx>
commit ae4fc532244b3bb4d86c397418d980b0c6be1dfd upstream.
On a TigerLake SoundWire platform, we see these warnings:
[ 27.360086] rt5682 sdw:0:25d:5682:0: ASoC: DAPM unknown pin MICBIAS
[ 27.360092] rt5682 sdw:0:25d:5682:0: ASoC: DAPM unknown pin Vref2
This is root-caused to the addition of a component prefix in the
machine driver. The tests in soc-dapm should account for a prefix
instead of reporting an invalid issue.
