6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@xxxxxxx>
[ Upstream commit c5ab94ea280a9b4108723eecf0a636e22a5bb137 ]
The conversion from the legacy event to MIDI2 UMP for RPN and NRPN
missed the setup of the channel number, resulting in always the
channel 0. Fix it.
Fixes: e9e02819a98a ("ALSA: seq: Automatic conversion of UMP events")
