genirq: Fix comment describing suspend_device_irqs()
The kerneldoc comment describing suspend_device_irqs() is currently misleading, because generally the function doesn't really disable interrupt lines at the chip level. Replace it with a more accurate one. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> LKML-Reference: <200907050022.35117.rjw@sisk.pl> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
