Pull localmodconfig update from Steven Rostedt:
 "While debugging the problem with localmodconfig and the ALSA codec
  modules all being set, I discovered a small bug in the dependency
  logic.

  If a config has a dependency based on its setting value,
  localmodcondig misses it.

  For example:

    config FOO
        default y if BAR || ZOO

  If FOO is needed for a module and is set to '=m', and so are BAR or
  ZOO, localmodconfig will not see that BAR or ZOO are also needed for
  the foo module, and will incorrectly disable them"
