[PATCH] PNPACPI: support shareable interrupts
ACPI supplies a "shareable" indication, but PNPACPI ignores it. If a PNP device uses a shared interrupt, request_irq() fails because the PNP driver can't tell whether to supply SA_SHIRQ. This patch allows PNP drivers to test (pnp_irq_flags(dev, 0) & IORESOURCE_IRQ_SHAREABLE) Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Adam Belay <ambx1@neo.rr.com> Cc: Matthieu Castet <castet.matthieu@free.fr> Cc: Li Shaohua <shaohua.li@intel.com> Cc: Len Brown <len.brown@intel.com> Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
