No, don't do that.  Use `git am` instead, possibly with the 3-way merge
options.

I would try checking out linux-next on a new branch, and then using `git
cherry-pick` to apply your patch.  That will try to apply the patch, and
give you merge conflicts if they don't apply.  You'll need to clean
those conflicts up and re-submit the resulting patch.  You may have to
re-do the patch if you can't get it to apply against linux-next.
