If anyone has any objections, please let me know. ------------------ From: Srinivas Kandagatla [ Upstream commit be1fae62cf253a5b67526cee9fbc07689b97c125 ] There is an issue around with error handling and graph management with the exising code, none of the error paths close the graph, which result in leaving the loaded graph in dsp, however the driver thinks otherwise. This can have a nasty side effect specially when we try to load the same graph to dsp, dsp returns error which leaves the board with no sound and requires restart. Fix this by properly closing the graph when we hit errors between open and close.
