Takashi Iwai 23b53d4417 ALSA: pcm: One more dependency for hw constraints ... The fix for a long-standing USB-audio bug required one more dependency variable to be added to the hw constraints. Unfortunately I didn't realize at debugging that the new addition may result in the overflow of the dependency array of each snd_pcm_hw_rule (up to three plus a sentinel), because USB-audio driver adds one more dependency only for a certain device and bus, hence it works as is for many devices. But in a bad case, a simple open always results in -EINVAL (with kernel WARNING if CONFIG_SND_DEBUG is set) no matter what is passed. Since the dependencies are real and unavoidable (USB-audio restricts the hw_params per looping over the format/rate/channels combos), the only good solution seems to raise the bar for one more dependency for snd_pcm_hw_rule -- so does this patch: now the hw constraint dependencies can be up to four.
