[PATCH 1/4] usb: gadget: f_midi: refactor state machine

This refactor results in a cleaner state machine code and as a result fixed a bug when packaging a MIDI-USB packet right after a non-conformant MIDI byte stream. Signed-off-by: Felipe F. Tonello --- drivers/usb/gadget/function/f_midi.c | 204 ++- 1 file changed,

[PATCH 2/4] usb: gadget: f_midi: added spinlock on transmit function

Since f_midi_transmit is called by both ALSA and USB frameworks, it can potentially cause a race condition between both calls. This is bad because the way f_midi_transmit is implemented can't handle concurrent calls. This is due to the fact that the usb request fifo looks for the next element and o
