Subject: soc/tegra: cbb: Move driver registration from pure_initcall to core_initcall
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=cd6e95e7ab29c4f67475e3eafef6f836f06eb0e8;p=thirdparty%2Fkernel%2Flinux.git

soc/tegra: cbb: Move driver registration from pure_initcall to core_initcall

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.
