BTW, if they read WM8753 datasheet instead of proposing to introduce
some ugly workarounds in kernel, they'd see that the codec itself
supports silent method of turning on/off. Needs further investigation
though. It can be even theoretically possible that the sound comes
from some glitch on stupid DL_GSM line. This matter needs further
investigation imho, but i can't see why it is considered to be
important and especially why it needs kernel work right now; sorry for
expressing my stupid opinion.
