Error building sample app: incompatible types when initializing type ‘int’ using type ‘k_timeout_t’

[jpwright]

Running into this issue when trying to build the sample app today. I am able to build the Zephyr blinky sample without issue.

I am using Ubuntu 19.10, rustc version 1.41.1, west version 0.7.2.

I get the same errors (and more after fixing that one) with the master branch of Zephyr. Try with v2.2.0 of Zephyr. Unfortunately the last several Zephyr releases have broken app compatibility, so I'll need to branch for 2.2 and port to 2.3.
