Merge tag 'gpio-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "Here are some accumulated patches with small fixes for this and that
  in a few GPIO drivers, and a more important fix to an #ifdef in the
  GPIO consumer header.

  Summary:

   - Get #ifdef's right in the <linux/gpio/consumer.h> header.

   - Minor fixes to tb10x, clps711x, bcm281xx, intel-mid and xtensa GPIO
     drivers"

* tag 'gpio-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpio: consumer.h: Move forward declarations outside #ifdef
  gpio: tb10x: GPIO_TB10X needs to select GENERIC_IRQ_CHIP
  gpio: clps711x: Add module alias to support module auto loading
  gpio: bcm281xx: Update MODULE_AUTHOR
  gpio: intel-mid: fix the incorrect return of idle callback
  gpio: xtensa: fix build when XCHAL_HAVE_CP is 0
