  "message": "ASoC: SOF: Intel: Fix stream cleanup on hw free\n\nField \"substream\" gets assigned during stream setup in\nhda_dsp_pcm_hw_params() but it is never cleared afterwards during\ncleanup procedure. Now, any non-pcm operation e.g.: compress can\nmistakenly make use of that pointer as it\u0027s bypassing all\n\"if (s-\u003esubstream)\" checks.\n\nNulling the pointer during hw_free operation ensures no wild pointers\nare left behind.\n\nFixes: cdae3b9a47aa (\"ASoC: SOF: Intel: Add Intel specific HDA PCM operations\")\nSigned-off-by: Cezary Rojewski \u003ccezary.rojewski@intel.com\u003e\nAcked-by: Pierre-Louis Bossart \u003cpierre-louis.bossart@linux.intel.com\u003e\nLink: https://lore.kernel.org/r/20200312120058.15057-1-cezary.rojewski@intel.com\nSigned-off-by: Mark Brown \u003cbroonie@kernel.org\u003e\n",
