From e81d9de531fb4c7f14344736bd7568c954e64e14 Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Thu, 24 Jan 2019 15:44:53 +0100 Subject: [PATCH] usb: udc-uclass: Fixed problem when no alias is defined in DT commit 801f1fa442 "dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports" changed the way the udevice if found. It uses the alias to find a udevice for a given USB port number. In the commit log it was stated that if no alias is provided, the bind order will be used instead. However it doesn't work. Fixing this by adding a call to uclass_get_device() if uclass_get_device_by_seq() fails.
