From c71320d0c445e01555a86fa6523609db47eeaef6 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 5 Jul 2009 00:22:34 +0200 Subject: [PATCH] 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.
