Revision e02f5f52cafbea013817d81f1acc4baf50d6324b authored by Bjorn Helgaas on 15 November 2007, 00:59:59 UTC, committed by Linus Torvalds on 15 November 2007, 02:45:41 UTC
"Luming Yu" <luming.yu@gmail.com> says: There is a "ttyS1 irq is -1" problem observed on tiger4 which cause the serial port broken. It is because that there is __no__ ACPI IRQ resource assigned for the serial port. So the value of the IRQ for the port is never changed since it got initialized to -1. If PNP supplies a valid IRQ, use it. Otherwise, leave port.irq == 0, which means "no IRQ" to the serial core.
