[PATCH AUTOSEL 6.10 078/197] ALSA: usb-audio: Replace complex quirk lines with macros

[Sasha Levin <sashal@xxxxxxxxxx>]

From: Takashi Iwai <tiwai@xxxxxxx>

[ Upstream commit d79e13f8e8abb5cd3a2a0f9fc9bc3fc750c5b06f ]

Apply the newly introduced macros for reduce the complex expressions
and cast in the quirk table definitions.  It results in a significant
code reduction, too.

There should be no functional changes.
