Subject: Problem with exclusive interrupt in hostap_cs

Jouni,

This was posted on the PCMCIA mailing list by Jack Schneider:

The two drivers being loaded are hostap_cs and xirc2ps_cs. The latter one is
coded to handle shared interrupts, but hostap_cs is not.

I would have no problem changing the driver interrupt registration in the
link->irq structure, but I was not quite sure how change prism2_interrupt() to
detect the shared case when the interrupt status register is 0xFFFF.

Could you please take a look at this?

Thanks,

Larry
