If anyone has any objections, please let me know. ------------------ From: Cédric Bellegarde [ Upstream commit 8a066a81ee0c1b6cdbd81393536c3b2d19ccef25 ] '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.
