From a3afbf5cc887fc3401f012fe629810998ed61859 Mon Sep 17 00:00:00 2001 From: Badhri Jagan Sridharan badhri@google.com Date: Fri, 7 Apr 2023 03:07:41 +0000 Subject: [PATCH] usb: gadget: udc: core: Prevent redundant calls to pullup
usb_gadget_connect calls gadget->ops->pullup without checking whether gadget->connected was previously set. Make this symmetric to usb_gadget_disconnect by returning early if gadget->connected is already set.
