Merge tag 'staging-3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

Pull staging driver fixes from Greg KH:
 "Here are some bugfixes for the staging and IIO drivers for 3.13-rc3.

  The resolve the vm memory issue in the tidspbridge driver, fix a
  much-reported build failure in an ARM driver, and some other IIO
  bugfixes that have been reported"

* tag 'staging-3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging:
  Staging: TIDSPBRIDGE: Use vm_iomap_memory for mmap-ing instead of remap_pfn_range
  Fix build failure for gp2ap020a00f.c
  iio: hid-sensors: Fix power and report state
