From b95d58eaf20eb33c245a2172ec4ecf46bd832309 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 30 Jan 2008 18:20:04 +0900 Subject: [PATCH] pci: allow multiple calls to pcim_enable_device() There's no reason not to allow multiple calls to pcim_enable_device(). Calls after the first one can simply be noop. All PCI resources will be released when the initial pcim_enable_device() resource is released. This allows more flexibility to managed PCI users.
