The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 9ca57518361418ad5ae7dc38a2128fbf4855e1a2 Mon Sep 17 00:00:00 2001 From: penghao Date: Wed, 18 Nov 2020 20:30:39 +0800 Subject: USB: quirks: Add USB_QUIRK_DISCONNECT_SUSPEND quirk for Lenovo A630Z TIO built-in usb-audio card 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. eg dmesg: .... [ 626.974091 ] usb 7-1.1: USB disconnect, device number 3 .... .... [ 1774.486691] usb 7-1.1: new full-speed USB device number 5 using xhci_hcd [ 1774.947742] usb 7-1.1: New USB device found, idVendor=17ef, idProduct=a012, bcdDevice= 0.55 [ 1774.956588] usb 7-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1774.964339] usb 7-1.1: Product: Thinkcentre TIO24Gen3 for USB-audio [ 1774.970999] usb 7-1.1: Manufacturer: Lenovo [ 1774.975447] usb 7-1.1: SerialNumber: 000000000000 [ 1775.048590] usb 7-1.1: 2:1: cannot get freq at ep 0x1 ....... 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.
