Please do not remove this function.  I am working on an enhancement to
the emu10k1 driver that uses it.

Thanks,

Do you need snd_emu10k1_sum_vol_attn, too?

Nope.  Any idea what this is/was for?  I poked around the OSS driver and
could not find a similar function.

IIRC, it came from the very old version of OSS emu10k1 driver.

OK.  I have added James to the cc.

OK.  If this code was in the original opensource.creative.com driver
then there is always the chance it embodies some knowledge of the
hardware that we don't have.  For example set_loop_stop, which was also
in the OSS driver but unused, can be used to start multiple channels in
sync.  But as long as the CVS history is available this should not be a
problem.

Yep.  The code is just to calculate X * ln2(Y) (or something like
that), so anyway it's not important for the hardware control.

I'd rather like to keep them with #if 0.
These functions will be needed when someone extends the DSP code.

They are intentionally non-static to allow ac97_patch.c functions to
access them (in future).  Please keep them so.


Otherwise the patch looks fine.
Thanks!

Applied to ALSA CVS now.
(Will be propagated to BK later...)
