From c181e0e00ff778623c7fda055fd404a06d2c7845 Mon Sep 17 00:00:00 2001 From: Daniel Ritz Date: Fri, 9 Sep 2005 13:03:25 -0700 Subject: [PATCH] fix pcmcia_request_irq() for multifunction card multifunction cards need to have the same irq assigned to both functions. the code tries that but fails because ret is still set to CS_IN_USE which results in the function having the CB irq assigned. yenta_set_socket then just changes the irq routing to use the PCI interrupt but the first functions irq handler is registered on an ISA interrupt. boom.
