  net/hyperv: Remove unnecessary kmap_atomic in netvsc driver
  staging/rtl8192e: Register against lib80211
  staging/rtl8192e: Convert to lib80211_crypt_info
  staging/rtl8192e: Convert to lib80211_crypt_data and lib80211_crypt_ops
  staging/rtl8192e: Add lib80211.h to rtllib.h
  staging/mei: add watchdog device registration wrappers
  drm/omap: GEM, deal with cache
  staging: vt6656: int.c, int.h: Change return of function to void
  staging: usbip: removed unused definitions from header
  staging: usbip: removed dead code from receive function
  staging:iio: Drop {mark,unmark}_in_use callbacks
  staging:iio: Drop buffer mark_param_change callback
  staging:iio: Drop the unused buffer enable() and is_enabled() callbacks
  staging:iio: Drop buffer busy flag
  staging:iio: Make sure a device is only opened once at a time
  staging:iio: Disallow modifying buffer size when buffer is enabled
  staging:iio: Disallow changing scan elements in all buffered modes
  staging:iio: Use iio_buffer_enabled instead of open coding it
  ...

Fix up conflict in drivers/staging/iio/adc/ad799x_core.c (removal of
module_init due to using module_i2c_driver() helper, next to removal of
MODULE_ALIAS due to using MODULE_DEVICE_TABLE instead).
