2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Ian Abbott <abbotti@mev.co.uk>
commit d1ce318496f5943d2cc5e20171fc383a59a1421f upstream.
The ni_labpc driver module only requests a shared IRQ for PCI devices, requesting a non-shared IRQ for non-PCI devices. As this module is also used by the ni_labpc_cs module for certain National Instruments PCMCIA cards, it also needs to request a shared IRQ for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus controller.
