I don't think the pinctrl drivers were designed to be removed.
And I thought the lack of a .remove callback in the driver blocks
the core from removing the device? Maybe I remember wrong...

Using a builtin_platform_driver should be enough to prevent it to be
removed.

Labbe, can you test it again on linux-next? Or at least with this patch
0c8c6ba00cbf pinctrl: sunxi: make bool drivers explicitly non-modular
from linux-pinctrl applied. This should fix it.

The problem is that it is already builtin_platform_driver()
