I actually prefer

git format-patch -v 3

that way you don't accidentally get something
other than "PATCH".



Another very, very minor remark.
It's usually a good idea to have a comma after
each initializer, that way you don't have to
change multiple lines when adding/removing something.

+struct platform_driver kirin_pcie_driver = {
+	.probe			= kirin_pcie_probe,
+	.driver			= {
+		.name			= "Kirin-pcie",
+		.of_match_table = kirin_pcie_match,
+		.suppress_bind_attrs = true
+	},
+};


Best regards,
Niklas
