From 8f758683a8077a13571f6ad57ccb4d7fe9e7b184 Mon Sep 17 00:00:00 2001 From: Gary Bisson Date: Thu, 6 Jan 2022 16:02:08 +0100 Subject: [PATCH] usb: gadget: dwc2_udc_otg: set ep's desc during enable/disable Fastboot support has been broken on platforms using dwc2 controller since the gadget gets its max packet size from it. This patch is the equivalent of 723fd5668ff which fixed the same issue but for the chipidea controller.
