commit 7eccc86e90f04a0d758d16c08627a620ac59604d upstream.
In case of attempts to compress playback something, for instance, when audio routing is not set up correctly, the audio DSP is left in inconsistent state because we are not doing the correct things in the error path of q6asm_dai_compr_set_params().
So, when routing is not set up and compress playback is attempted the following errors are present (simplified log):
q6routing routing: Routing not setup for MultiMedia-1 Session q6asm-dai dais: Stream reg failed ret:-22 q6asm-dai dais: ASoC error (-22): at snd_soc_component_compr_set_params() on 17300000.remoteproc:glink-edge:apr:service@7:dais
After setting the correct routing the compress playback will always fail:
q6asm-dai dais: cmd = 0x10db3 returned error = 0x9 q6asm-dai dais: DSP returned error[9] q6asm-dai dais: q6asm_open_write failed q6asm-dai dais: ASoC error (-22): at snd_soc_component_compr_set_params() on 17300000.remoteproc:glink-edge:apr:service@7:dais
0x9 here means "Operation is already processed". The CMD_OPEN here was sent the second time hence DSP responds that it was already done.
Turns out the CMD_CLOSE should be sent after the q6asm_open_write() succeeded but something failed after that, for instance, routing setup.
Fix this by slightly reworking the error path in q6asm_dai_compr_set_params().
Tested on QRB5165 RB5 and SDM845 RB3 boards.
