Subject: [can-next-rfc 09/10] can: peak_usb: pcan_usb_get_serial(): unconditionally assign serial_number
Date: Tue, 6 Apr 2021 13:16:21 +0200 [thread overview]
Message-ID: <20210406111622.1874957-10-mkl@pengutronix.de> (raw)
In-Reply-To: <20210406111622.1874957-1-mkl@pengutronix.de>
The function serial_number is only called from one location with a
valid serial_number pointer. Remove not needed NULL pointer check.
