Subject: [PATCH 2/6] serial: meson: remove dead code in meson_uart_change_speed
Date: Sun, 16 Apr 2017 22:10:59 +0200 [thread overview]
Message-ID: <32194c6b-0c4f-a7f0-1a61-edfaffbc63c7@gmail.com> (raw)
In-Reply-To: <d16f695a-42b2-dfc2-0e53-df110f5a8389@gmail.com>
val is set in both branches of the if clause, therefore the two
removed lines are dead code.
