Merge tag 'omap-for-v3.17/fixes-not-urgent-signed' of... 

Merge tag 'omap-for-v3.17/fixes-not-urgent-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical

Merge non-urgent omap fixes from Tony Lindgren:

Fixes for omaps that were not considered urgent enough for the
rc series. Mostly a fix for GPMC allocation and omap5 ABB
(Adaptive Body Bias).

* tag 'omap-for-v3.17/fixes-not-urgent-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: omap2+: gpmc-nand: Use dynamic platform_device_alloc()
  omap16xx: Removes fixme no longer needed in ocpi_enable()
  ARM: dts: OMAP5: Add device nodes for ABB
  ARM: omap2+: usb-tusb6010.c: Cleaning up variable is set more than once
