Subject: [PATCH 3/6] serial: meson: remove unneeded variable assignment in meson_serial_port_write
Date: Sun, 16 Apr 2017 22:13:25 +0200 [thread overview]
Message-ID: <c1371fc8-ebc2-0d14-e409-02e2fbf3ba94@gmail.com> (raw)
In-Reply-To: <d16f695a-42b2-dfc2-0e53-df110f5a8389@gmail.com>
AML_UART_TX_EN is set in meson_uart_startup and there's no place in
the driver where it gets cleared. Therefore we don't have to set it
here.
