  [PATCH 1/3] usb: gadget: f_midi: constify snd_rawmidi_ops structures Julia Lawall <Julia.Lawall@lip6.fr> - 2017-08-15 10:40 +0200

#1711957 — [PATCH 1/3] usb: gadget: f_midi: constify snd_rawmidi_ops structures

These snd_rawmidi_ops structures are only passed as the third
argument of snd_rawmidi_set_ops.  This argument is const, so the
snd_rawmidi_ops structures can be const too.

Done with the help of Coccinelle.
