[PATCH 00/23] sandbox: support COMPILE_TESTing drivers

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We have quite a few drivers marked for COMPILE_TEST in tree now.
I compile-tested them so far under ARCH_STM32MP and ARCH_IMX.

The end goal was to be able to build them for non-ARM as well,
especially ARCH=sandbox, which, being a hosted platform, can
easily be compiled with clang-analyzer or other static analyzers.

This series adds the last few bells and whistles to COMPILE_TEST
these drivers under sandbox as well.

The five last patches address the first few issues found by
clang-analyzer. There are still hundreds more in need of triage:

(Check it out; control flow visualization is pretty! j/k to navigate)

Cheers,
Ahmad (23):
