From 09cc900632400079619e9154604fd299c2cc9a5a Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 30 Mar 2023 19:24:30 +0300 Subject: PCI: Introduce pci_dev_for_each_resource() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of open-coding it everywhere introduce a tiny helper that can be used to iterate over each resource of a PCI device, and convert the most obvious users into it. While at it drop doubled empty line before pdev_sort_resources(). No functional changes intended.
