usb: core: notify disconnection when core detects disconnect

2014-11-04T03:29:55Z

It is safe to call notify disconnect when the usb core thinks the device is disconnected. This commit also fixes one bug found at below situation: we have not enabled usb wakeup, we do system suspend when there is an usb device at the port, after suspend, we plug out the usb device, then plug in device again. At that time, the nofity disconnect was not called at current code, as the controller doesn't know the usb device was disconnected during the suspend, but USB core knows the port has changed during that periods. So to fix this problem, and let the usb core call notify disconnect. Cc: 3.17+ Signed-off-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

usb: core: need to call usb_phy_notify_connect after device setup

2014-11-03T23:48:45Z

Since we notify disconnecting based on the usb device is existed (port_dev->child, the child device at roothub is not NULL), we need to notify connect after device has been registered. This fixes a bug that do fast plug in/out test, and the notify_disconnect is not called due to roothub child is NULL and the enumeration has failed.
