Pull GPIO fix from Linus Walleij:
 "Compile problem fix for Tegra,

  Sorry to send this in the last minute but Ingo says this build failure
  is very prominent so I'm not going to wait for v4.7 before sending it.

  It is a case of COMPILE_TEST causing more problems than it solves and
  I'm already swearing about me shooting myself in the foot with that
  gun :("
