From 5e56bc06e18dfc8a66180fa369384b36e2ab621a Mon Sep 17 00:00:00 2001 From: Christian Gromm Date: Fri, 24 Apr 2020 17:16:34 +0200 Subject: most: core: use function subsys_initcall() 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.
