Subject: serial: allocate minor device numbers for serial_txx9 driver
From: Atsushi Nemoto <anemo@xxxxxxxxxxxxx>
The serial_txx9 driver have abused device numbers (major 4, minor 128) if
CONFIG_SERIAL_TXX9_STDSERIAL was not set. This patch makes the driver
allocate minor numbers from major 204 (Low-density serial ports). I
suppose a typical user of this driver set CONFIG_SERIAL_TXX9_STDSERIAL to Y
(i.e. use "ttyS0"), so this patch would not cause big compatibility issue.
