Jason Zhang 8e6ac8c6ba ALSA: pcm: fix out-of-bounds in snd_pcm_state_names commit `2b3a7a302c` upstream. 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) (...)

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
