The ad7291 driver is in a reasonable shape. It does not use non-standard API/ABI
and there are no major style issues with the driver. So this patch moves it out
of staging.

There is one small warning from checkpatch which is also fixed in this patch.
The patch also sorts the #include directives in alphabetical order.

This patch introduces the use of devm_ioremap_resource. It does away
with call to request_mem_region and the error checking on
platform_get_resource. Also, the calls to free the allocated resources
like release_mem_region and iounmap are done away with. The ret variable
in the probe function is also eliminated. Also, a bug is fixed as the
goto in the error handling of request_mem_region should not have
called release_mem_region which releases a resource that has not been
allocated.

Currently the STMicroelectronics sensors only support one single
platform data item: configuration of the DRDY (data ready) pin
for a particular design. Augment the core to prioritize and take
this information from the device tree if the parent device has an
assigned device node, else fall back to passed in platform data
(usually the default data).

to the sampling frequency becomes available to in kernel users of the

This particular conversion was made more complicated by the shared library
and the fact that a number of the drivers do not actually have support for
setting or reading the sampling frequency.  The hardware, in those cases
investigated supports it. It's just never been implemented.
