commit a337c355719c42a6c5b67e985ad753590ed844fb upstream.
It's been reported that the runtime PM on KONTRON SinglePC (PCI SSID 1734:1232) caused a stall of playback after a bunch of invocations. (FWIW, this looks like an timing issue, and the stall happens rather on the controller side.)
As a workaround, disable the default power-save on this platform.
