Test the volume of usb audio whether actually it works and adjusts
the resolution value according to it.
Some USB audio devices report a lower resolution than it reacts.
The only possible check is to write and read a volume value.

snd_ctl_add() kfree's the kcontrol already if we fail there,
so this driver is currently doing a double kfree.

`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration. This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).
While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

Checking a pointer for NULL before calling kfree() on it is redundant,
kfree() deals with NULL pointers just fine.
This patch removes such checks from sound/
This patch also makes another, but closely related, change.
It avoids casting pointers about to be kfree()'ed.

This patch adds a proc file for the SB Audigy 2 NX which shows the
connection status of the various jacks. Unfortunately, no SPDIF input
frequency (yet).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
