From 55e18c6b6d426818032d5e0f9d88d87fd2a8ae30 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ilpo=20J=C3=A4rvinen?= Date: Mon, 6 Jun 2022 13:04:28 +0300 Subject: [PATCH] serial: imx: Remove serial_rs485 sanitization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The driver provides different rs485_supported for the case where RTS is not available making it unnecessary to handle it in imx_uart_rs485_config.
