Description

ASoC: qcom: q6asm: drop DSP responses for closed data streams

In the Linux kernel, the following vulnerability has been resolved:

ASoC: qcom: q6asm: drop DSP responses for closed data streams

'Commit a354f030dbce ("ASoC: qcom: q6asm: handle the responses

after closing")' attempted to ignore DSP responses arriving

after a stream had been closed.

However, those responses were still handled, causing lockups.

Fix this by unconditionally dropping all DSP responses associated with

closed data streams.
