Subject: usb: dwc2: host: avoid resetting lx_state to L3 during disconnect
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=9afaf75508b0bec6ef38b83d97aa40701cc1b00c;p=deliverable%2Flinux.git

usb: dwc2: host: avoid resetting lx_state to L3 during disconnect

When a device is disconnected, lx_state must not be changed since the
device may be disconnected whereas controller is still powered.
