Ah nevermind looks like there is already a way to get this info via the
controller sysfs :
/sys/devices/soc/a80.ssusb/a80.dwc3/gadget/sound/card7/midiC7D0/.
Let's drop this patch

I didn't realize that having function in func_inst was actually android
only. I think we can track card and device values in f_midi_opts in that
case, and update them as they change. I'll put up a fix soon.

Hi Jerry,
Thank you for the patch! Yet something to improve:

An f_midi instance will have a corresponding native
device in /dev/snd/midiC%dD%d where the first number
is the number of the sound card and the second is the
number of the device. Expose both of these through
configfs so the user can find the correct sound device.
The configfs attrs are read only
