Hi Tony,

Thanks for your patch.

It looks like this is breaking some builds with the following error:

oeqa.utils.subprocesstweak.OETestCalledProcessError: Command '. /srv/pokybuild/yocto-worker/qemux86-64/build/build/tmp/work/qemux86_64-poky-linux/core-image-sato/1.0/testsdkext/environment-setup-core2-64-poky-linux > /dev/null; devtool add kernel-module-hello-world https://git.yoctoproject.org/git/kernel-module-hello-world;' returned non-zero exit status 1.
...
ERROR: Bitbake Fetcher Error: FetchError("Recipe uses a floating tag/branch 'master' for repo 'git.yoctoproject.org/git/kernel-module-hello-world' without a fixed SRCREV yet doesn't call bb.fetch2.get_srcrev() (use SRCPV in PV for OE).", None)

https://autobuilder.yoctoproject.org/valkyrie/#/builders/30/builds/2199
https://autobuilder.yoctoproject.org/valkyrie/#/builders/16/builds/2247

Can you have a look at this error please?

Best regards,
Mathieu
