Aha. That's the reason I receive these messages. I've wondering why I
receive them.

Well, I don't mind to receive them because it's a good information for
me to get current state of ALSA core functionality. If I had some
spare time, I was also going to fix it. But currently I have little
time for it due to my development for my minor hardwares...

(Actually, Iwai-san posted patches to fix them at incredibly pace. I
can't follow his pace, because I'm working for ALSA in my free time.)
