+Subject: [PATCH 10/12] Revert "spa: improve the AEC interface"
+
+This reverts commit c5c9ecdd87225ecd4978e9f6176a8a6d1fdd4252.
+Upstream-Status: Inappropriate[meson version dependent]
+
+This patch had to be reverted as it is dependent on
+9386c70b3a2cc2df6aabfd7b6a6bc1d7ec873bd1 which needs
+higher meson version.
