Merge branch 'staging-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
* 'staging-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (466 commits)
net/hyperv: Add support for jumbo frame up to 64KB
net/hyperv: Add NETVSP protocol version negotiation
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).
