That is likely because your review-andy branch contain a whole-bunch
of asus-wmi patches.

Since this is a patch fixing a regression this should go to the fixes
branch. As the other patches so far are only in your review-andy branch
it is probably best to merge this patch to for-next + fixes first and
then rebase the set you have in review-andy on top, so that this can go
to fixes without getting a merge conflict when the rest of the patches
show up...

Regards,

Hans
