SubjectRe: [PATCH v13 5/8] usb:gadget: Add SuperSpeed support to the Gadget Framework

perhaps better phrasing would be: Enable Super Speed support

maybe i didnt look too closely, but it seems like very little even
depends upon this Kconfig option in the actual source. only the
"gadget_is_superspeed()", and that is used lightly. so i wonder how
useful this is even having ...

i know you're just following existing style, but i wonder if these all
shouldnt just be min_t(u16, ...)

please dont split string literals over multiple lines

isnt that the default behavior already ? so these two lines are pointless ?

erm, seems unrelated to this patchset ? did this sneak in by accident ?

multiline comments should read:
