Jason Zhang 2b3a7a302c ALSA: pcm: fix out-of-bounds in snd_pcm_state_names ... The pcm state can be SNDRV_PCM_STATE_DISCONNECTED at disconnect callback, and there is not an entry of SNDRV_PCM_STATE_DISCONNECTED in snd_pcm_state_names. This patch adds the missing entry to resolve this issue. cat /proc/asound/card2/pcm0p/sub0/status That results in stack traces like the following: [ 99.702732][ T5171] Unexpected kernel BRK exception at EL1 [ 99.702774][ T5171] Internal error: BRK handler: f2005512 [#1] PREEMPT SMP [ 99.703858][ T5171] Modules linked in: bcmdhd(E) (...)
