Takashi Iwai e1a3a981e3 ALSA: pcm: Remove WARN_ON() at snd_pcm_hw_params() error ... snd_pcm_hw_params() (more exactly snd_pcm_hw_params_choose()) contains a check of the return error from snd_pcm_hw_param_first() and _last() with snd_BUG_ON() -- i.e. it may trigger WARN_ON() depending on the kconfig. This was a valid check in the past, as these functions shouldn't return any error if the parameters have been already refined via snd_pcm_hw_refine() beforehand. However, the recent rewrite introduced a kmalloc() in snd_pcm_hw_refine() for removing VLA, and this brought a possibility to trigger an error. As a result, syzbot caught lots of superfluous kernel WARN_ON() and paniced via fault injection. As the WARN_ON() is no longer valid with the introduction of kmalloc(), let's drop snd_BUG_ON() check, in order to make the world peaceful place again.
