Subject: [PATCH 3/5] usb: isp1760: do not reset retval
Date: Thu, 19 Aug 2021 19:09:27 +0100	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

We do not really need to reset retval before get used bellow.
This will avoid the clang-analyzer warning:

drivers/usb/isp1760/isp1760-hcd.c:1919:2: warning: Value stored to 'retval' is never read [clang-analyzer-deadcode.DeadStores]
        retval = 0;
