Hence the code is never going to be modular. So using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Also add an inclusion of init.h, as that was previously implicit. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of subsys_initcall (which seems to make sense for IPC code) will thus change this registration from level 6-device to level 4-subsys (i.e. slightly earlier). However no impact of that small difference is expected.
