Subject: [PATCH 2/5] drivers/usb/dwc3: zynqmp: only free reset gpio if we have one
Date: Wed, 30 Aug 2023 16:03:31 +0200	[thread overview]
Message-ID: <20230830140349.10801-3-lists@steffen.cc> (raw)
In-Reply-To: <20230830140349.10801-1-lists@steffen.cc>

From: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>

This gpio is optional so undonditionally freeing it will crash.
