checks.
This new function allows us to perform debug checks in the helper to ensure
that the overrun does not occur. Use it in all the simple cases where
either a static buffer or a structure is used in the drivers.

This complex cleanup.h use case of conditional guards has proved
to be more trouble that it is worth in terms of false positive compiler
warnings and hard to read code.
Move directly to the new claim/release_direct() that allow sparse
to check for unbalanced context.

Add support for AD7770, AD7771, AD7779 ADCs. The device is capable of
sending out data both on DOUT lines interface,as on the SDO line.
The driver currently implements only the SDO data streaming mode. SPI
communication is used alternatively for accessing registers and streaming
data. Register accesses are protected by crc8.
