ALSA: au88x0: Fix assignment in if condition

PCI AU88x0 driver code contains a lot of assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.

This patch is merely for coding-style fixes. A potential real fix is
about the PCI AGP bridge management refcount in addition while spotted
out during conversions.

ALSA: au88x0: More constifications

ALSA: au88x0: Fix overlapped PCM pointer

au88x0 hardware seems returning the current pointer at the buffer
boundary instead of going back to zero. This results in spewing
warnings from PCM core.

This patch corrects the return value from the pointer callback within
the proper value range, just returning zero if the position is equal
or above the buffer size.

Linux-2.6.12-rc2

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!
