Subject: [PATCH v2 8/9] usb: cdns3: core: removed overwriting some error code
Date: Mon, 13 Jul 2020 12:05:53 +0200 [thread overview]
Message-ID: <20200713100554.28530-9-pawell@cadence.com> (raw)
In-Reply-To: <20200713100554.28530-1-pawell@cadence.com>
Some error code can be preserved, so we can remove overwriting
error code returned by some functions.
