SOF interrupt is unconditionally disabled in process_control_request()

Operating System

Linux

Board

Firmware

RPI Pico SDK

What happened ?

During processing of a SETUP message in process_control_request() there is an unconditional call to dcd_sof_enable(rhport, false). This ignores the SOF user state set with tud_sof_cb_enable(true).
The workaround is to do a:

tud_sof_cb_enable(false);
tud_sof_cb_enable(true);

in tud_mount_cb() as well as tud_umount_cb(). This comes with the penalty of a potential SOF miss.

SOF should only be disabled if there is really no SOF user.

How to reproduce ?

As stated above.
