[FFmpeg-devel] [PATCH] avformat/riffdec: remove invalid sample rate check

[Viraaj Raulgaonkar]

Sample rates up to 2^31 - 1 are considered valid, while greater values
are invalid.  Removing the check potentially allows the sample rate
to be decoded in all cases instead of halting demux for values
greater than 2^31 - 1.

Fixes Trac ticket #11361.
