From: Sascha Hauer <s.hauer@pengutronix.de> We just got a common helper for parsing the rs485 specific device tree properties. Use it and drop the open coded parser. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Uwe Kleine-K?nig <redacted> --- Changes since v1: - drop paragraph in commit log that of_get_rs485_mode is more strict as this is wrong in v2. drivers/tty/serial/omap-serial.c | 12 +----------- 1 file changed, 1 insertion(+), 11 deletions(-)
