Subject[PATCH] PM / irq: Fix comment describing suspend_device_irqs()
DateSun, 5 Jul 2009 00:22:34 +0200
From: Rafael J. Wysocki <rjw@sisk.pl>

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.
