Commit "driver core: platform: set mod_name in driver registration" will set struct device_driver's mod_name member for platform driver registration. For a driver to be registered with its mod_name set, module_kset needs to be initialized, which currently happens in a subsys_initcall in param_sysfs_init(). The tegra cbb drivers register themselves before module_kset init, in a pure_initcall. This works currently because lookup_or_create_module_kobject(), which dereferences module_kset via kset_find_obj(), is not called if mod_name is not set, which is the case now.
So in preparation for the commit "driver core: platform: set mod_name in driver registration", move tegra cbb driver registration to core_initcall level, and commit "kernel: param: initialize module_kset in a pure_initcall" will move module_kset init to pure_initcall level, ensuring module_kset init happens before tegra cbb driver registration.
