-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.
