commit a4915b3b1e1daad4bbd04fc62e8a66f4da28958d Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Mon May 26 04:35:48 2014 +1000
superio/winbond/w83627ehg: Remove pnp_enter symbol from global
Part 2/2: Break this poor relationship between boards and Super I/O support to be more well-defined. The Super I/O pnp_entry/exit functions should not be exposed into the global name-space, rather should be static-local.
