From edf76f8307c350bcb81f0c760118a991b3e62956 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Wed, 18 May 2011 10:39:04 +0100 Subject: 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.
