[ Upstream commit 0c3ad39b791c2ecf718afcaca30e5ceafa939d5c ]
Many entries in the USB-audio quirk tables have relatively complex
expressions. For improving the readability, introduce a few macros.
Those are applied in the following patch.

commit 15b7a03205b31bc5623378c190d22b7ff60026f1 upstream.
There can be concurrent accesses to line6 midibuf from both the URB
completion callback and the rawmidi API access. This could be a cause
of KMSAN warning triggered by syzkaller below (so put as reported-by
here).
This patch protects the midibuf call of the former code path with a
spinlock for avoiding the possible races.

[ Upstream commit 03898691d42e0170e7d00f07cbe21ce0e9f3a8fa ]
At the code refactoring of USB-audio quirk handling, I assumed that
the quirk entries of Stanton ScratchAmp devices were only about the
device name, and moved them completely into the rename table.
But it seems that the device requires the quirk entry so that it's
probed by the driver itself.
This re-adds back the quirk entries of ScratchAmp, but in a
minimalistic manner.

commit b7b7e1ab7619deb3b299b5e5c619c3e6f183a12d upstream.
USB-audio driver puts SNDRV_CHMAP_SL and _SR as left and right
surround channels for UAC1 channel map, respectively. But they should
have been SNDRV_CHMAP_RL and _RR; the current value *_SL and _SR are
rather "side" channels, not "surround". I guess I took those
mistakenly when I read the spec mentioning "surround left".
This patch corrects those entries to be the right channels.

For shutting up spurious KMSAN uninit-value warnings, just replace
kmalloc() calls with kzalloc() for the buffers used for
communications. There should be no real issue with the original code,
but it's still better to cover.
