+Subject: [PATCH] Fix unbalanced parentheses in FAudio.c
+
+Commit b5916945b90d ("Dont assert on WMA buffer and
+FAUDIO_FORMAT_EXTENSIBLE type") introduced unbalanced parentheses,
+which breaks builds using HAVE_WMADEC.
+
+Given the change made in the aforementioned commit, this balances
+parentheses by adding a third closing parenthesis after the reworked
+conditions.
