Finally, after 10 kernels built, I've obtained the result. Here is the output:

    Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking

    Commit 61f5acea8737 ("Bluetooth: btusb: Restore QCA Rome suspend/resume fix
    with a "rewritten" version") applied the USB_QUIRK_RESET_RESUME to all QCA
    USB Bluetooth modules. But it turns out that the resume problems are not
    caused by the QCA Rome chipset, on most platforms it resumes fine. The
    resume problems are actually a platform problem (likely the platform
    cutting all power when suspended).

    The USB_QUIRK_RESET_RESUME quirk also disables runtime suspend, so by
    matching on usb-ids, we're causing all boards with these chips to use extra
    power, to fix resume problems which only happen on some boards.

    This commit fixes this by applying the quirk based on DMI matching instead
    of on usb-ids, so that we match the platform and not the chipset.

    Here is the /sys/kernel/debug/usb/devices for the Bluetooth module:
