From d26e7fc3d907db19f7e25126476cb416f0527592 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 21 Nov 2023 12:36:40 -0600 Subject: x86/pci: Rename pci_mmcfg_check_reserved() to pci_mmcfg_reserved() "pci_mmcfg_check_reserved()" doesn't give a hint about what the boolean return value means. Rename it to pci_mmcfg_reserved() so testing "if (pci_mmcfg_reserved())" makes sense. Update callers to treat the return value as boolean instead of comparing with 0.
