X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=cd0e641c8da3c763f1f4b838a9bc30f1297f68d0;p=deliverable%2Flinux.git

usb: dwc2: gadget: set op_state in vbus_session call

Some device may have external id pin control enabled, so op_state
will not be set on id pin interrupt change.
Thus, ensure op_state is set to peripheral during vbus detection.
