From e7f9e1fca9b0563e5e83c5d2c5164bdda5948227 Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Wed, 21 Oct 2020 14:17:31 +0200 Subject: [PATCH] usb: dwc3: Handle case where setup_phy is not needed If CONFIG_PHY is not enabled then the dwc3_setup_phy() returns ENOTSUPP which can be still valid and intentional so modify error check to handle this -ENOTSUPP. The same error handling exists in drivers/usb/host/xhci-dwc3.c already added by commit d648a50c0a27 ("dwc3: move phy operation to core.c").
