Please do not use "This commit/patch/change", but imperative mood. See

All other Tegra drivers are non-selectable, so you are introducing
completely different style. This needs explanation WHY in the commit msg.

Also, since you are changing things around, then I suggest to finally
enable proper COMPILE_TEST for all tegra pinctrl. Unless I mistaken,
it's impossible to compile test currently anything from Tegra pinctrl...
Actually let me take a look, maybe I will do it for several platforms.

Why this cannot be module_platform_driver()?
