[PATCH 5/9] ASoC: qcom: q6asm: handle the responses after closing

[Srinivas Kandagatla]

For record path, multiple read requests are queued to dsp in advance.
However when data stream is closed, the pending read requests are rejected
by the dsp and a response is sent to the driver, this case is not handled
in the driver resulting in errors like below

q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: command[0x10dac] not expecting rsp
q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: command[0x10dac] not expecting rsp
q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: command[0x10dac] not expecting rsp

This is same for both write and eos.

Fix this by allowing ASM_DATA_CMD_READ_V2, ASM_DATA_CMD_EOS and
ASM_DATA_CMD_WRITE_V2 as expected response.
