[PATCH] ALSA: usb-audio: Apply implicit feedback mode for BOSS devices

[Lucas]

Does it help if you use this line in "static const struct
snd_usb_implicit_fb_match capture_implicit_fb_quirks[] = {":
        IMPLICIT_FB_BOTH_DEV(0x0582, 0x0109, 0x05, 0x01), /* BOSS eBand
JS-8 */

For it, I attempted using your specific 0x05 ASYNC OUT endpoint address
this time.

I may be wrong, but I think Takashi's current patches are reading endpoint
addresses directly from the hardware, and if so your BOSS eBand JS-8 would
work if that line does.

Takashi would know best, though, so I'm bracing myself for any corrections.
