Contribution to Apache NuttX

Hi! Thank you for wanting to contribute to Apache NuttX.

Guidelines

In order to help us review your contribution successfully it is very important you follow these guidelines:

Use descriptive commit messages and, if the change warrants further description, do add a separate paragraph like so:
```
<first line (up to ~80 characters)>

<more paragraphs here>
```
- The first line should have a prefix to give context (unless context is really clear), such as:
```
<keyword>: <message>
i.e sched: Fixed compiler warning
```
Be sure to fill in the pull-request template with meaningful content (be very descriptive, take your time). Do not remove these sections or ignore them.
- Tip: if you create a commit message as above, the first line will be automatically used as PR title and the rest added to the description. Use it as a starting point to describe your PR.
You should follow NuttX C Coding Standard
- Your code will be automatically checked by GitHub Continuous Integration (CI) system. If you see the "check" step fails, it is possible that this happens due to style errors.
- Note that we require you to solve these issues and adapt all modified files even if you didn't introduce the problem yourself (this way, every contribution gets us closer to compliance).
