[PATCH v2 0/3] ALSA: usb-audio: add module param device_quirk_flags

[Cryolitia PukNgae via B4 Relay <devnull+cryolitia.uniontech.com@kernel.org>]

As an implementation of what has been discussed previously[1].

I would like to add a new param. The existed param
`static unsigned int quirk_flags[SNDRV_CARDS]` seems to related to
some sequence the card probed. To be honest, I havn't fully understood
it. And it seems hard to improve it while keeping compatibility.
