If anyone has any objections, please let me know. ------------------ From: Srinivas Kandagatla commit 4b4db09f283df65d780bc7cee66cb4a7e9bf4770 upstream. Fix error handling in q6asm_dai_compr_set_params() and q6asm_dai_prepare() for both CMD_CLOSE and q6asm_unmap_memory_regions(). In both the functions, we are doing q6asm_audio_client_free in failure cases, which means if prepare or set_params fail, we can never recover. Now open and close are done in respective dai_open/close functions.
