ACPI: AC: fix some coding style issues
Fix some coding style issues reported by checkpatch.pl, including the
following types:
ERROR: "foo * bar" should be "foo *bar"
ERROR: code indent should use tabs where possible
WARNING: Block comments use a trailing */ on a separate line
WARNING: braces {} are not necessary for single statement blocks
WARNING: void function return statements are not generally useful
WARNING: CVS style keyword markers, these will _not_ be updated
