[ Upstream commit 5e56bc06e18dfc8a66180fa369384b36e2ab621a ]
This patch replaces function module_init() with subsys_initcall(). It is needed to ensure that the core module of the driver is initialized before a component tries to register with the core. This leads to a NULL pointer dereference if the driver is configured as in-tree.
