Subject: [PATCH 1/2] usb: dwc3: drd: Don't free non-existing irq
Date: Sun, 29 Mar 2020 17:09:59 -0700	[thread overview]
Message-ID: <c2892b14b915f3e8bd7df91cd44f126abd887bd2.1585526614.git.thinhn@synopsys.com> (raw)
In-Reply-To: <cover.1585526614.git.thinhn@synopsys.com>

If the driver is configured to use DRD role-switch, it's not OTG. There
won't be OTG irq to free. Check for dwc->otg_irq before freeing it.
