[PATCH] usb3: Fixed usb3 device is not detected in s0 when hotplug usb3 disk under S3

2016-08-17 Thread Huang, Huki
When end user inserts a usb3 device and put dut to s3. Then hotplug the usb3 disk under s3. The device will be lost upon resuming from s3. There is a corner case that the hub->change_bits for the usb3 port is not set when usb port change event happens. This will cause hub driver ignore the device
