Hi all,

I'm a little bit confused about the build errors reported by Intel's test bot and I'd really appreciate human input.
This is the first patch I submit, so apologies in advance if I missed a basic step.

I compiled and tested every patch before submission and they all compiled and worked on this tree:
git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid.git

After receiving this email, I followed the instructions attached to build it and indeed it failed.
However, I reverted my changes and the kernel still didn't compile.

Is this something I need to fix?

Thank you very much in advance,
José Expósito
