Add a USB_QUIRK_DISCONNECT_SUSPEND quirk for the Lenovo TIO built-in
usb-audio.when A630Z going into S3,the system immediately wakeup 7-8
seconds later by usb-audio disconnect interrupt.to avoids the issue.
Seeking a better fix, we've tried a lot of things, including:
- Check that the device's power/wakeup is disabled
- Check that remote wakeup is off at the USB level
- All the quirks in drivers/usb/core/quirks.c e.g. USB_QUIRK_RESET_RESUME,
USB_QUIRK_RESET, USB_QUIRK_IGNORE_REMOTE_WAKEUP, USB_QUIRK_NO_LPM.
but none of that makes any difference.
There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.
Introduce a quirk to disable the port during suspend when the modem is
detected.
