sound: usb-audio: fix uninitialized variable with M-Audio MIDI interfaces
commit e156ac4c571e3be741bc411e58820b74a9295c72 upstream.
Fix the snd_usbmidi_create_endpoints_midiman() function, which forgot to
set the out_interval member of the endpoint info structure for Midiman/
M-Audio devices. Since kernel 2.6.24, any non-zero value makes the
driver use interrupt transfers instead of bulk transfers. With EHCI
controllers, these random interval values result in unbearably large
latencies for output MIDI transfers.
