Hi Sergio and Yanteng, Thank you for taking care of this! > MT7620 PCIe host controller driver can be built as a module but there is no > 'MODULE_LICENSE()' specified in code, causing a build error due to missing > license information. > > ERROR: modpost: missing MODULE_LICENSE() in drivers/pci/controller/pcie-mt7621.o > > Fix this by adding 'MODULE_LICENSE()' to the driver. > > Fixes: 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host controller driver") > Signed-off-by: Yanteng Si <siyanteng@xxxxxxxxxxx> > Signed-off-by: Sergio Paracuellos <sergio.paracuellos@xxxxxxxxx> > --- > drivers/pci/controller/pcie-mt7621.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/drivers/pci/controller/pcie-mt7621.c b/drivers/pci/controller/pcie-mt7621.c > index 9cf541f5de9c..a120a61ede07 100644 > --- a/drivers/pci/controller/pcie-mt7621.c > +++ b/drivers/pci/controller/pcie-mt7621.c > @@ -561,3 +561,5 @@ static struct platform_driver mt7621_pci_driver = { > }, > }; > builtin_platform_driver(mt7621_pci_driver); > + > +MODULE_LICENSE("GPL v2"); A question here about the builtin_platform_driver() use in this driver, especially since it's set as tristate in Kconfig, thus I am not sure if using builtin_platform_driver() over module_platform_driver() is correct? Unless this is more because you need to reply on device_initcall() for the driver to properly initialise? Otherwise, Reviewed-by: Krzysztof Wilczyński <kw@xxxxxxxxx> Krzysztof
