From 9871b0e5d0f9a5479dddfc5d3a9f47924a996421 Mon Sep 17 00:00:00 2001 From: Venkatesh Yadav Abbarapu Date: Wed, 9 Aug 2023 09:03:50 +0530 Subject: [PATCH] usb: dwc3: Fix remove function if there is no ulpi_reset gpio As ulpi_reset gpio is now optional, we need to check it when doing the 'dwc3_generic_remove' function. Check if it is declared before accessing the ulpi_reset.
