ACPI battery: fix async boot oops
> BUG: unable to handle kernel NULL pointer dereference at (null) What happens is that the battery module's init sections are being freed before the async callback (which was marked __init) has run. This theory is supported by the fact that the bad RIP value is a vmalloc address. The immediate fix is to make this a non-init call. (A better long-term fix is of course to wait with init-section unloading until a module's async initcalls have been run, which would allow us to discard this function which is still only run once, after all. Perhaps a new async_initcall() function for the async/module API, if this is needed for other modules in the future?)
