Message-Id: <1253396244-7885-70-git-send-email-gregkh@suse.de> Date: Sat, 19 Sep 2009 14:37:15 -0700 From: Greg Kroah-Hartman <gregkh@...e.de> To: linux-kernel@...r.kernel.org Cc: Jiri Slaby <jirislaby@...il.com>, Greg Kroah-Hartman <gregkh@...e.de> Subject: [PATCH 70/79] tty: Char: mxser, use THRE for ASPP_OQUEUE ioctl From: Jiri Slaby <jirislaby@...il.com> 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.
