Subject: [PATCH 0/7] staging:iio:ade7854: Cleanup on I2C/SPI code

This patchset reworks the I2C/SPI code from meter module. The set of
patches try to reduce the code duplication and make the communication
reliable. The current version of the module had many code duplications,
which make the code more error-prone and hard to read. Jonh Syne
identified some wrong error handling and fixed it in his patches; in
this series of patches I analyzed Jonh's fixes, and use it in the new
code.

It is important to highlight that meter module is under observation, due
to the lack of hardware and the old design of the chip. However, John
has the hardware for testing and interest to help to update the code
[1]. As a result, this patchset represents the first work effort to
update the meter module in the staging.
