Subject: [PATCH tty v3 4/6] serial: 8250: Set cons_flow on port registration
Date: Fri, 17 Apr 2026 12:30:17 +0206 [thread overview]
Message-ID: <20260417102423.40984-5-john.ogness@linutronix.de> (raw)
In-Reply-To: <20260417102423.40984-1-john.ogness@linutronix.de>
Since console flow control policy is no longer part of uart_port.flags,
explicitly set the policy for the port.
