CHIRP PR Guidelines

The following must be true before PRs can be merged:

1. All tests must be passing. The "PR Checks" job is speculative and failure doesn't always indicate a critial problem, but generally it needs to pass as well.
2. Commits should be rebased (or simply rebase-able in the web UI) on current master. Do not put merge commits in a PR.
3. Commits in a single PR should be related. Squash intermediate commits into logical units (i.e. "fix tests" commits need not survive on their own). Keep cleanup commits separate from functional changes.
4. Major new features or bug fixes should reference a CHIRP issue in the commit message. Do this with the pattern Fixes #1234 or Related to #1234 so that the ticket system links the commit to the issue.
5. Please write a reasonable commit message, especially if making some change that isn't totally obvious (such as adding a new model, adding a feature, etc). The first line of every commit is emailed to the users' list after each build. It should be short, but meaningful for regular users (examples: "thd74: Fixed tone decoding" or "uv5r: Added settings support"). There should be a blank line after the first, followed by additional text so that it gets formatted properly for the mailing list.
6. New drivers should be accompanied by a test image in tests/images (except for thin aliases where the driver is sufficiently tested already). All new drivers must use MemoryMapBytes.
7. All files must be GPLv3 licensed or contain no license verbiage. No additional restrictions can be placed on the usage (i.e. such as noncommercial).
8. Do not add new py2-compatibility code (No new uses of six, future, etc).

You need to rebase (not merge) this in order to pass the check. Also, please read the PR guidelines and fix the commit message for this in a suitable way.

Thanks!

This is a conflict with master since this change is already present

I guess you're trying to add another BT fingerprint, but "there is such a print" does not make sense. Can you please replace this comment with the firmware version that matches the one you're trying to add?
