The patch titled
serial: keep the DTR setting for serial console.
has been removed from the -mm tree. Its filename was
serial-keep-the-dtr-setting-for-serial-console.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: serial: keep the DTR setting for serial console.
From: Yinghai Lu <Yinghai.Lu@Sun.COM>
with reverting "x86, serial: convert legacy COM ports to platform devices",
we will have the serial console before the port is probled again.
uart_add_one_port==>uart_configure_port==>set_mcttrl(port, 0) will clear
the DTR setting by uart_set_options(). then I will lose my output from
serial console again.
So try to keep DTR in uart_configure_port()
