From eb14120f743d29744d9475bffec56ff4ad43a749 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sun, 7 Mar 2010 12:21:16 +0100 Subject: pcmcia: re-work pcmcia_request_irq() Instead of the old pcmcia_request_irq() interface, drivers may now choose between: - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq. - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will clean up automatically on calls to pcmcia_disable_device() or device ejection. - drivers still not capable of IRQF_SHARED (or not telling us so) may use the deprecated pcmcia_request_exclusive_irq() for the time being; they might receive a shared IRQ nonetheless.
