From a75b7b68ef73685784781d6d2bc416b6dac20969 Mon Sep 17 00:00:00 2001 From: Jiri Slaby <jirislaby@gmail.com> Date: Thu, 10 Sep 2009 12:20:08 +0200 Subject: [PATCH] tty: Char: mxser, use THRE for ASPP_OQUEUE ioctl In moxa specific ASPP_OQUEUE ioctl command, they apparently want only know whether there is space in transmitter hold register. So switch UART_LSR_TEMT to UART_LSR_THRE in that specific case according to the change in 1.14 moxa drivers.
