Jerry Zhang 2d19cdc1cb usb: gadget: f_midi: Use snd_card_free_when_closed with refcount ... Currenly, f_midi_free uses snd_card_free, which will wait until the user has released the sound card before returning. However, if the user doesn't release the sound card, then f_midi_free can block for an arbitrary amount of time, which also blocks any gadget operations on that thread. Instead, we can use snd_card_free_when_closed which returns before all handles are released. Since f_midi can be accessed through rmidi if usb_put_function is called before release_card_device, add refcounting to f_midi_free and have rawmidi's private free call it. The f_midi memory is only kfreed when usb_put_function and release_card_device have both been called.
