[026/115] staging: comedi: ni_labpc: Use shared IRQ for PCMCIA card
From: Greg KH
Date: Tue Feb 15 2011 - 21:11:13 EST
2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Ian Abbott <abbotti@xxxxxxxxx>
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.
