hi Takashi, I have a doubt regarding this korg1212. snd_korg1212_free_pcm is just making korg1212->pcm as NULL. But are we not supposed to release the allocated memory ? in snd_pcm_new we are allocating memory.
The allocated memories by snd_pcm_new() are freed automatically. The private_free callback is for extra memory that is allocated in the outside. But in this case, it's the chip object that will be freed snd_korg1212_dev_free(), so snd_korg1212_free_pcm() doesn't do anything. (Actually it can be dropped.)
