Subject: [PATCH v1 6/9] usb: at91_udc: remove useless NULL check
Date: Tue, 20 Nov 2018 21:07:11 +0100 [thread overview]
Message-ID: <20181120200714.3692-7-linux@rempel-privat.de> (raw)
In-Reply-To: <20181120200714.3692-1-linux@rempel-privat.de>
if _ep or ep is NULL, we would get at least in two places
before this test a NULL pointer dereference.
