2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------ From: Daniel Mack <[email protected]> commit 53dea36c70c1857149a8c447224e3936eb8b5339 upstream. Don't rely on the codec's channels_min information to decide wheter or not allocate a substream's DMA buffer. Rather check if the substream itself was allocated previously.
