[hatari-devel] MIDI IRQ handling bug

Hi Nicolas,

Current Hatari IRQ handling is buggy for MIDI. Midi_UnInit() disables 
MIDI IRQ, but Midi_Init() does not enable it, only calling Midi_Reset() 
does, which does not happen on MIDI device change.

(Similarly to handling of RS232, SCC & printer devices, MIDI device 
change at run-time does not trigger reset.)

I tried calling Midi_Reset() directly from Midi_Init(), but that freezes 
Hatari at startup (to somewhere in interrupt handling code).

Attached patch seems to work, but I assume all the things done by 
Midi_Reset() should not be done just on device change.

Could you look into what's the correct fix?
