Implicit feedback on BOSS GT-1, the saga continues...

[Lucas]

Geraldo, you've made testing kernel patches for me quite easy, so thanks to
you!  And I'm happy to report that your patch, which I manually applied
because I forgot to remove the "if (false)" change, is working perfectly!
I am now able to use the, minimally mentioned, Takashi UA-101 MIDI patch
with the UA-101 set to USB 1.1 mode, on the same kernel that has perfectly
clean Boutique D-05 playback.  The Takashi UA-101 patch is here:
https://bugzilla.kernel.org/show_bug.cgi?id=212477, just in case there's
curiosity.  :)

It seems to me, that since the UA-101 in (USB 1.1 mode) isn't compatible
with the "if (false)" endpoint.c method, it would have to be matched for
exclusion, assuming we would ever be able to more simply match with
Roland's/BOSS' Vendor ID of 0x0582.  I still think that would be the
ultimate patch because, as far as I'm aware, all new Roland/BOSS devices
use minimally-differing forms of this implicit feedback quirk.

Thanks. again, for everything Mike, Geraldo, & Takashi!
