Author: Anton Khirnov <[email protected]> Committer: Anton Khirnov <[email protected]> Date: Wed Mar 6 10:02:50 2013 +0100 wmaprodec: return an error, not 0, when the input is too small. Returning 0 may result in an infinite loop in valid calling programs. A decoder should never return 0 without producing any output.
