+Subject: [PATCH] ASoC: cs42l81: initialize stereo playback mixer sources
+
+The ASP slot geometry is configured at power-up but the playback mixer
+source selectors are left to their previous values. This can retain a
+silent or duplicated channel after codec reset or firmware use.
+
+Follow AppleCS42L81Audio::updateRouting by assigning mb00 and mb01 to
+ASP RX slots 0 and 1 before enabling the playback path. Keep the
+existing stereo power and volume sequence unchanged.
+
+[Orchard: from orchard PR #124, commit bef17c42; unchanged]
