4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Sakamoto <[email protected]> commit ce925f088b979537f22f9e05eb923ef9822ca139 upstream. After allocating model-dependent data, ALSA OXFW driver has memory leak of the data at error path. This commit releases the data at the error path.
