I *think* it has something to do with the fact that we currently have two "mtk_pcie_driver" definitions: one in pcie-mediatek.c and the other in pcie-mediatek-gen3.c, and apparently we want to make them different. I can buy that. But there are many other symbols with the same names in the two drivers, e.g., mtk_pcie_probe(), mtk_pcie_remove(). Why is mtk_pcie_driver special? Maybe it's important that the of_device_id[] names be different? This change is fine; I'd just like the commit log to have a little more explanation of *why* it is useful. Nit: I don't think this distinguishes the *controllers*. It looks like it distinguishes the *drivers*. > Signed-off-by: Jianjun Wang <jianjun.wang@mediatek.com> > --- > Changes in v2: > Remove the changes in Kconfig description and update the commit message. > --- > drivers/pci/controller/pcie-mediatek-gen3.c | 12 ++++++------ > 1 file changed, 6 insertions(+), 6 deletions(-) > > diff --git a/drivers/pci/controller/pcie-mediatek-gen3.c b/drivers/pci/controller/pcie-mediatek-gen3.c > index 7705d61fba4c..6745076a02b9 100644 > --- a/drivers/pci/controller/pcie-mediatek-gen3.c > +++ b/drivers/pci/controller/pcie-mediatek-gen3.c > @@ -1011,21 +1011,21 @@ static const struct dev_pm_ops mtk_pcie_pm_ops = { > mtk_pcie_resume_noirq) > }; > > -static const struct of_device_id mtk_pcie_of_match[] = { > +static const struct of_device_id mtk_pcie_gen3_of_match[] = { > { .compatible = "mediatek,mt8192-pcie" }, > {}, > }; > -MODULE_DEVICE_TABLE(of, mtk_pcie_of_match); > +MODULE_DEVICE_TABLE(of, mtk_pcie_gen3_of_match); > > -static struct platform_driver mtk_pcie_driver = { > +static struct platform_driver mtk_pcie_driver_gen3 = { > .probe = mtk_pcie_probe, > .remove = mtk_pcie_remove, > .driver = { > - .name = "mtk-pcie", > - .of_match_table = mtk_pcie_of_match, > + .name = "mtk-pcie-gen3", > + .of_match_table = mtk_pcie_gen3_of_match, > .pm = &mtk_pcie_pm_ops, > }, > }; > > -module_platform_driver(mtk_pcie_driver); > +module_platform_driver(mtk_pcie_driver_gen3); > MODULE_LICENSE("GPL v2"); > -- > 2.18.0 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
