[ Upstream commit 90e10a1fcd9b24b4ba8c0d35136127473dcd829e ]
This driver exports a regmap tied to the platform device (as opposed to a syscon, which exports a regmap tied to the OF node). Because of this, the driver can never be unbound, as that would destroy the regmap. Use builtin_platform_driver_probe() to enforce this limitation.
