Arnd reported a regression caused by this patch.  It seems to be fixed
by commit 1c390eb360c3 ("usb: musb: fix Kconfig regression"), also
tagged for stable.  However, it looks like this patch was actually
dropped from all the stable trees as Arnd also pointed out that the
original problem was relatively harmless.
