ALSA: ice1724 - Dynamic MIDI TX irq control MIDI_TX IRQ seems always pending when any bytes on FIFO is available. Thus, it's better to enable MPU_TX only when any bytres are really stored in the substream, and disables immediately when the queue becomes empty. Signed-off-by: Takashi Iwai <tiwai@suse.de>
