Add HAVE_TRUSTED_KEYS to th trusted-keys/Kconfig. 2. The use and purpose of HAVE_TRUSTED_KEYS. If you read your commit message, do you see anything at all concerning the code change? It only tells a story about something that is not properly being defined to be "hard to read", which is no rationale to change anything at all in the kernel. If you put factors more focus on being as straight and easy to get in the commit messages, it will also improve the round-trip time between sending the patch set and getting reviewed, because people with limited time at their hands tend to pick the low-hanging fruit first.

Checking if at least one valid trust source is selected does not scale and becomes hard to read. This improves this in preparation for the DCP trust source.
