From b91da7308171ac4ad2623d371f37288dafbb3bdc Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sun, 4 Feb 2024 17:28:58 -0300 Subject: [PATCH] PCI: endpoint: Make pci_epf_bus_type const Now that the driver core can properly handle constant struct bus_type, move the pci_epf_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
