sound: rawmidi: disable active-sensing-on-close by default
Sending an Active Sensing message when closing a port can interfere with the following data if the port is reopened and a note-on is sent before the device's timeout has elapsed. Therefore, it is better to disable this setting by default. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
