Merge tag 'gpio-v4.7-4' of git://git./linux/kernel/git/linusw/linux-gpio

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"
