Since3107b952f5("sound: Merge PCM_ALIVE() with PCM_REGISTERED()"), pcm_unregister() is gated on PCM_REGISTERED(), so it cannot run unless pcm_register() has already succeeded, which means drivers will leak resources if a failure happened prior to this. Reintroduce PCM_ALIVE(), but test dev rather than the lock. pcm_init() assigns dev before anything else, so it can tell us whether pcm_init() has run or not. Make sure to clear it in pcm_unregister() so that a second call to pcm_unregister() cannot double-free. While here, publish to sndstat(4) only once pcm_register() has succeeded.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
