Subject: pcmcia: ti: regression cannot get IRQ

Hello

I was trying to boot again my old compaq armada 7400 laptop and the network card is unusable.

Last known working kernel is 4.16.18.
First known bad kernel is 4.17.19

The interesting log is:
[    3.503348] yenta_cardbus 0000:00:0c.0: ISA IRQ mask 0x0698, PCI irq 0
