um: Implement um_free_irq()
Instead of using chip->release() we can achieve the same using a simple wrapper for free_irq(). We have already um_request_irq(), so um_free_irq() is the perfect counterpart. Signed-off-by: Richard Weinberger <richard@nod.at> Reviewed-by: Thomas Gleixner <tglx@linutronix.de>
