4.2.8-ckt5 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------ From: Takashi Iwai <ti...@suse.de> commit cc85f7a634cfaf9f0713c6aa06d08817424db37a upstream. NULL user-space buffer can be passed even in a normal path, thus it's not good to spew a kernel warning with stack trace at each time. Just drop snd_BUG_ON() macro usage there.
