irq: Export functions to allow modular irq drivers
Export handle_simple_irq, irq_modify_status, irq_alloc_descs, irq_free_descs and generic_handle_irq to allow their usage in modules. First user is IIO, which wants to be built modular, but needs to be able to create irq chips, allocate and configure interrupt descriptors and handle demultiplexing interrupts. [ tglx: Moved the uninlinig of generic_handle_irq to a separate patch ] Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Link: http://lkml.kernel.org/r/%3C1305711544-505-1-git-send-email-jic23%40cam.ac.uk%3E Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
