From 4e643671f53173bf0f95f11e3b5a1872ffe029d3 Mon Sep 17 00:00:00 2001 From: Jun Li Date: Mon, 25 Jan 2021 21:43:52 +0800 Subject: [PATCH] usb: gadget: set correct usb_configuration for os_desc_config The current way to set cdev->os_desc_config is wrong if user restart fastboot, as the old config is not used anymore and new allocated usb_configuration will be used, so set the os_desc_config while usb_add_config.
