As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

Building and Running
********************
This project outputs to the console. It can be built and executed
on QEMU as follows:
.. zephyr-app-commands::
:zephyr-app: samples/drivers/crypto
:host-os: unix
:board: qemu_x86
:goals: run
:compact:
