From c9c13ba428ef90a9b408a6cdf874e14ab5754516 Mon Sep 17 00:00:00 2001 From: Denis Efremov Date: Sat, 28 Sep 2019 02:43:08 +0300 Subject: PCI: Add PCI_STD_NUM_BARS for the number of standard BARs Code that iterates over all standard PCI BARs typically uses PCI_STD_RESOURCE_END. However, that requires the unusual test "i <= PCI_STD_RESOURCE_END" rather than something the typical "i < PCI_STD_NUM_BARS". Add a definition for PCI_STD_NUM_BARS and change loops to use the more idiomatic C style to help avoid fencepost errors.
