Felipe F. Tonello e1e3d7ec5d usb: gadget: f_midi: pre-allocate IN requests ... This patch introduces pre-allocation of IN endpoint USB requests. This improves on latency (requires no usb request allocation on transmit) and avoid several potential probles on allocating too many usb requests (which involves DMA pool allocation problems). This implementation also handles better multiple MIDI Gadget ports, always processing the last processed MIDI substream if the last USB request wasn't enought to handle the whole stream.
