ALSA: seq: ump: Fix seq port updates per FB info notify
[ Upstream commit aaa55faa2495320e44bc643a917c701f2cc89ee7 ]
update_port_infos() is called when a UMP FB Info update notification
is received, and this function is supposed to update the attributes of
the corresponding sequencer port. However, the function had a few
issues and it brought to the incorrect states. Namely:
- It tried to get a wrong sequencer info for the update without
correcting the port number with the group-offset 1
- The loop exited immediately when a sequencer port isn't present;
this ended up with the truncation if a sequencer port in the middle
goes away
This patch addresses those bugs.
