[PATCH 2/2] ALSA: usb-audio: Generic application of implicit fb to Roland/BOSS devices

[Lucas]

That patch worked perfectly for both devices I noticed the issue on (the
Roland INTEGRA-7 and R-26).

Although unrelated, I think the other issue with the EIDROL UA-101 in full
speed mode (USB 1.1) is new since trying the 5.12.0-rc8-next-20210422
kernel branch.  Prior to that, I'd been continually patching updates to the
mainline 5.11.9 source.

Thanks again, Takashi!,
