[PATCH] Fixing most Roland-related devices' USB audio

[Lucas]

Thanks for the encouragement and wisdom.  I hope your additions, and mine,
work out in the end.  A real hurdle with tasking everyone with patching for
their devices, aside from having probably long since given up hope for use
of the device on GNU/Linux, is the amount of disparate forums they voiced
their issues on.  There's also the daunting likelihood that select few
music creators actually would decide to compile their own kernels to see if
a problem is fixed, let alone feel comfortable enough applying a patch.

I hadn't realized this was a list to drum up testers, or that every change
needs to be tested fully.  I thought it was a direct path to possible
acceptance for inclusion in the kernel, if reasonable doubts are considered.

I hope they'll let me sidestep that huge, unreasonable, undertaking, as my
test implicit feedback "fix" for the UA-4FX (which doesn't need it) proved
it still functions as perfectly as without it.  That should mean that for
the devices that don't require this patch, but which had been accidentally
added, no harm is done.  I can't really see myself as owner of all these
devices someday... ;)

Thanks again, Geraldo!,
