This patch introduces the use of devm_kzalloc and does away with the
kfrees in the probe and remove functions. Also, a couple of labels and
the initial assignment of the ret variable in the probe function are
removed.

Broadcom hardware supports auto-adjustment of TX power depending on the
currently used rate. So far all calculations were handled without any
helpers (API) using big arrays and magic offsets.
It seems Broadcom recently decided to clean this up by developing PPR.
Their wlc_ppr.h can be found in open parts of the SDK.
As we plan to implement support for rate-based TX power it makes sense
to also implement our version of PPR as well.

But at76_delete_device() does usb_put_dev(priv->dev) itself

* TI ADC128S052 ADC
* BMC150 Accelerometer
* exynos ADC driver gains support for s3c24xx and s3c64xx parts.

Driver removals
* Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple
basis that they drivers just provided a register write function with
no compliant user space ABI whatsoever. Much better to drop them and
start again for these in the fullness of time.
Core Enhancements
* Join together neighbouring elements in the demux units that feeds
the binary interfaces. This cuts down on the number of individual
copies needed when splitting out individual channels from the incoming
channel scans.
* Other demux related cleanups such as using roundup instead of a local
implementation.
Cleanups
* Drop an unnecessary double setting of the owner field in xilinx adc.
* Some more patches to use managed (devm) interfaces to cut down on
complexity of removal code.
* adis16060 coding style fixlets.
* Fix some incorrect error returns in the Xilinx ADC driver.
* Coding style fixlets for various accelerometer drivers.
* Some sparse warning fixes to do with endianness and sign of variables.
* Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer
in hid-sensor-magn-3d by dropping the relevant code.

The uSCSI from Newer Technology is a SCSI-USB converter with USB ID 06ca:2003.
Like several other SCSI-USB products, it's a Shuttle Technology OEM device.
Without a suitable entry in unusual-devs.h, the converter can only access the
(single) device with SCSI ID 0. Copying the entry for device 04e6:0002 allows
it to work with devices with other SCSI IDs too.
There are currently six entries for Shuttle-developed SCSI-USB devices in
unusual-devs.h (grep for euscsi):
04e6:0002 Shuttle eUSCSI Bridge USB_SC_DEVICE, USB_PR_DEVICE
04e6:000b Shuttle eUSCSI Bridge USB_SC_SCSI, USB_PR_BULK
