From b75cece1a79a6259185442004e040511ed3a7341 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 4 Feb 2014 00:40:46 +0100 Subject: [PATCH] ACPI / hotplug / PCI: Simplify hotplug_event() A few lines of code can be cut from hotplug_event() by defining and initializing the slot variable at the top of the function, so do that.
