ALSA: usb-audio: Manage number of rawmidis globally
We're going to create rawmidi objects for MIDI 2.0 in a different code
from the current code for USB-MIDI 1.0. As a preliminary work, this
patch adds the number of rawmidi objects to keep globally in a
USB-audio card instance, so that it can be referred from both MIDI 1.0
and 2.0 code.

snd_usbmidi_output_open() has a check of the NULL port with
snd_BUG_ON(). snd_BUG_ON() was used as this shouldn't have happened,
but in reality, the NULL port may be seen when the device gives an
invalid endpoint setup at the descriptor, hence the driver skips the
allocation. That is, the check itself is valid and snd_BUG_ON()
should be dropped from there. Otherwise it's confusing as if it were
a real bug, as recently syzbot stumbled on it.

sound: usb: remove third argument of usb_maxpacket()
The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).
N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.

ALSA: usb-audio: Clear MIDI port active flag after draining
When a rawmidi output stream is closed, it calls the drain at first,
then does trigger-off only when the drain returns -ERESTARTSYS as a
fallback. It implies that each driver should turn off the stream
properly after the drain. Meanwhile, USB-audio MIDI interface didn't
change the port->active flag after the drain. This may leave the
output work picking up the port that is closed right now, which
eventually leads to a use-after-free for the already released rawmidi
object.
This patch fixes the bug by properly clearing the port->active flag
after the output drain.

ALSA: usb-audio: Drop snd_BUG_ON() from snd_usbmidi_output_open()
commit ad72c3c3f6eb81d2cb189ec71e888316adada5df upstream.
snd_usbmidi_output_open() has a check of the NULL port with
snd_BUG_ON().
ALSA: usb-audio: Drop snd_BUG_ON() from snd_usbmidi_output_open()
commit ad72c3c3f6eb81d2cb189ec71e888316adada5df upstream.
snd_usbmidi_output_open() has a check of the NULL port with
snd_BUG_ON(). snd_BUG_ON() was used as this shouldn't have happened,
but in reality, the NULL port may be seen when the device gives an
invalid endpoint setup at the descriptor, hence the driver skips the
allocation. That is, the check itself is valid and snd_BUG_ON()
should be dropped from there. Otherwise it's confusing as if it were
a real bug, as recently syzbot stumbled on it.
