From 2f686f1d9beee135de6d08caea707ec7bfc916d4 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 19 May 2017 14:40:50 -0500 Subject: [PATCH] PCI: Correct PCI_STD_RESOURCE_END usage PCI_STD_RESOURCE_END is (confusingly) the index of the last valid BAR, not the *number* of BARs. To iterate through all possible BARs, we need to include PCI_STD_RESOURCE_END.
