Since commit 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host controller driver") the MT7621 PCIe host controller driver is built as a module but no MODULE_*() attributes were specified, causing a build error due to missing license information. At the same time, modpost complains once these drivers become modules. ERROR: modpost: missing MODULE_LICENSE() in drivers/pci/controller/pcie-mt7621.o ERROR: modpost: "mips_cm_unlock_other" [drivers/pci/controller/pcie-mt7621.ko] undefined!
