From 32050e631c4498dd2b32c584980747f71b3a255d Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Fri, 24 Jan 2025 14:29:14 +0200 Subject: [PATCH] ASoc: SOF: topology: connect DAI to a single DAI link The partial matching of DAI widget to link names, can cause problems if one of the widget names is a substring of another. E.g. with names "Foo1" and Foo10", it's not possible to correctly link up "Foo1". Modify the logic so that if multiple DAI links match the widget stream name, prioritize a full match if one is found.
