Signing CLA does not seem to work, I've done it multiple times already, to no avail.

@Hallot We have fix for this already submitted in our internal merge requests queue. It will soon reflect to github as well. You can probable close this PR.

@Hallot ,

Thanks again for this, the internal fix for this should be pushed to GitHub very soon. (We cherry-picked this commit but also implemented this feature for the new SPI Flash API added in V4.0).

For the record:

Signing CLA does not seem to work, I've done it multiple times already, to no avail.

It doesn't matter in this case, but for future reference this didn't work because the email address used for the commit isn't associated with your GitHub account (if you look at the commit shown above you can see that there's anonymous GitHub user shown as the committer). So the CLA bot has no way to know who the committer for this change is.
