Linus Torvalds 144b5ae3e3 GPIO fixes for the v4.7 cycle: ...

- It was discovered that too many parts of the kernel does not
   respect gpiod_to_irq() returning zero for an invalid IRQ.
   While this gets fixed, we need to make it return negative
   errorcodes again.
 
 - Harden the library a bit when passed error pointers. It is
   a bug to use these, but let's be helpful and warn the users.
 
 - Fix an uninitialized spinlock in the 104-idi-48 driver.

Pull GPIO fixes from Linus Walleij:
 "More GPIO fixes.  Most prominent the gpiod_to_irq() fix brought to my
  attention by Hans de Goede.  The hardening patch is a consequence of
  the reasoning around that bug.

   - It was discovered that too many parts of the kernel does not
     respect gpiod_to_irq() returning zero for an invalid IRQ.  While
     this gets fixed, we need to make it return negative errorcodes
     again.

   - Harden the library a bit when passed error pointers.  It is a bug
     to use these, but let's be helpful and warn the users.

   - Fix an uninitialized spinlock in the 104-idi-48 driver"
