Subject: [PATCH] tty: serial: fsl_lpuart: remove the count initialization as it is not needed
Date: Mon, 18 Apr 2022 10:18:44 +0800 [thread overview]
Message-ID: <20220418021844.29591-1-sherry.sun@nxp.com> (raw)
No need to initialize the count variable in lpuart_copy_rx_to_tty(),
so let's remove it here.
