Merge tag 'iio-for-3.14a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new features, drivers and cleanups for IIO in the 3.14 cycle.
This mostly consists of patches that didn't quite make the last cycle. Lots
of interesting things under review currently.

Core:
- Add devm_iio_device_register/unregister.  I took some convincing on whether
  there would be many devices that really were simple enough to need no
  explicit actions on removal.  Turns out there are some.
- Move some stray docs to above the relevant implemenation.
- Drop a redundant repeated check on the fact the trigger has actually changed
  when there is a userspace attempt change it.

Drivers:
New drivers
- Freescale MPL3115A2 Pressure / temperature sensor

New functionality
- hid_sensors: add sensitivity support.

DT bindings
- tsl2563
- hmc5843

Cleanups
- Drop unused scan_type from viperboard adc driver.
- devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130,
  adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018
  and ad2s1200.  Note that this was proposed in a number of other drivers
  and this revealed a number of missorderings in remove functions.  Also for
  now I have blocked this on any device that any hardware suspend suport on
  the basis that we probably want to power down devices if they have no driver
  support loaded.

There are still many rts5208/5288 card readers being used, but no
drivers are supported them in kernel now. This driver can make a
great convenience for people who use them.

Many other rts-series card reader are supported by mfd driver, but due
to much difference with others, rts5208/5288 can not add into mfd driver
pretty now, so we provide a separated driver here to support the device.

The return variable of request_code_segment() is used uninitialized if
the argument boot_case is false, this patch fixes it.

FYI, in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE 0x1001.

Merge structures typedef struct tagSTxShortBufHead and the members of
struct vnt_tx_datahead_ab to form single structure vnt_tx_short_buf_head.

Remove the duplicate members in struct vnt_beacon_buffer already in
typedef struct tagSTxShortBufHead.

This removes the need for any pointer arithmetic.

Error handling code in gdm_usb_probe() deallocates all resources,
but calls usb_get_dev(usbdev) and returns error code after that.

The patch fixes it and, by the way, several other issues:
- no need to use GFP_ATOMIC in probe();
- return -ENODEV instead of -1;
- kmalloc+memset -> kzalloc
