[PATCH] ALSA: usb-audio: Add quirk flag for Creative Stage SE

[PATCH] ALSA: usb-audio: Add quirk flag for Creative Stage SE

[Yejung Kim]

The UAC mixer on Creative Stage SE (041e:3289) returns invalid/constant
GET_CUR volume values, causing ALSA to treat it as a sticky mixer and
to disable it.

Add a quirk table entry applying QUIRK_FLAG_MIXER_GET_CUR_BROKEN to
allow volume controls to function correctly.

... rather not, I dropped again.

This flag is no longer needed with the latest 7.3-rc, and the quirk
has been dropped / renamed.

Please retest with the latest 7.3-rc.  Or it'll be fixed in the
upcoming 7.2.x update, I suppose.


thanks,

Takashi
