The report from Intel's test robot is a false positive.

Patch is applied to the wrong git tree. It is based on the testing
branch of linux-can-next:
https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/log/?h=testing

> And when submitting patch, we suggest to use '--base' as documented in

I did so (c.f. the base-commit and prerequisite-patch-id tags at the
bottom of the patch). While the base-commit was taken into account,
the prerequisite-patch-id tags seem to have been ignored.

FYI, I used the below command to generate the patch.
git format-patch --base=bff6f1db91e330d7fba56f815cdbc412c75fe163 -v6
-o patch/v6 HEAD~1

Thanks, nice catch!
CONFIG_SYSFS is an expert setting, I totally missed that one. Took me
actually a couple of minutes navigating in the menuconfig to find how
to remove the option.

The root cause is actually on CONFIG_BQL (which depends on
CONFIG_SYSFS).
Reference: https://elixir.bootlin.com/linux/latest/source/include/linux/netdevice.h#L636

Will send a v7 patch right after.

Out of curiosity, how did you find this? Did you find it during a code
review or did you just happen to have a .config with CONFIG_SYSFS


Yours sincerely,
Vincent Mailhol

During code review, I found that the dql had a ifdef CONFIG_SYSFS.
