[PATCH] serial: serial_txx9 driver update
Update the serial_txx9 driver. * Configurable manumum port number. (SERIAL_TXX9_NR_UARTS) * Remove some code which is unneeded if CONFIG_PM=n. * Use PCI_DEVICE() for pci device id table and make it const. * Do not include <asm/irq.h> Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
