[ARM] 3530/1: PXA Mainstone: prevent double enable_irq() in pcmcia
Patch from Thomas Gleixner The mainstone board pcmcia interrupt have been enabled via setup_irq() and the following socket check calls enable_irq again. Set the NOAUTOEN flag so the interrupt is not automatically enabled in setup_irq() Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
