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. Signed-off-by: Penghao <penghao@uniontech.com> --- drivers/usb/core/quirks.c | 4 ++++ 1 file changed, 4 insertions(+)
