sound fixes for 6.1-rc5

Things look calming down, as this contains only a few small fixes.

- Fix for a corner-case bug with SG-buffer page allocation helper

Hmm. I don't know that this came in through this particular pull
request, but I don't seem to have seen it before:

Nov 11 14:32:37 xps13 kernel:
snd_hda_intel 0000:00:1f.3: Too many BDL entries:
buffer=2097152, period=65536

there's six of those lines in my logs (two batches of three, five
seconds apart).

I don't see any negative side effects aside from the messages, and
sound seems to work fine, but since I don't think I've ever seen this
one before I thought I'd just mention it.

I also haven't been using this laptop on a while - an arm64 Fedora
uboot update broke my M2 boot, so I'm temporarily back to using my
trusty old xps13.

So while it's new to me, the issue that introduced it may not be
particularly new.

Google does show that the message itself has been happening for others
for a long time. But I checked with 'journalctl', and it hasn't
happened on this particular machine before.

It might be a non-kernel change that triggers it, of course.

Wooh, that must be the last change in the memalloc helper for
non-contiguous pages :-< Admittedly the fix was a bit premature,
sorry for the mess.

Below is the quick workaround. I'm going to send another PR soon
later.


thanks,

Takashi

Subject: [PATCH] ALSA: memalloc: Try dma_alloc_noncontiguous() at first

The latest fix for the non-contiguous memalloc helper changed the
allocation method for a non-IOMMU system to use only the fallback
allocator. This should have worked, but it caused a problem sometimes
when too many non-contiguous pages are allocated that can't be treated
by HD-audio controller.

As a quirk workaround, go back to the original strategy: use
dma_alloc_noncontiguous() at first, and apply the fallback only when
it fails, but only for non-IOMMU case.

We'll need a better fix in the fallback code as well, but this
workaround should paper over most cases.
