Yup, this looks like it's coming in through Lee's MFD tree, a series from
Gwendal to update cros_ec_commands.h.

784dd15c930f mfd: cros_ec: Fix event processing API

That commit is in the immutable branch for v5.3 here:
 git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git ib-mfd-cros-v5.3

I'd recommend the chrome-platform tree since we'll be pulling in that IB too
for some other refactoring Enric is working on.

Thanks,
Benson
