Wait - you seemed to want to apply that on your tree because of
dependencies (which I can understand). So how do you suggest to
proceed?
You can apply your original version of the patch on your tree, but
then it'll collapse when it'll meet iwlwifi-next.git.
I can try to have the modified version of the patch into 4.1 but I
doubt I'll make it. If I do make it, it'd allow you to work on top of
4.1 whenever that'll be ready? What is your timeline?

Or maybe you can pull iwlwifi-next (which would be odd I have to say)?
What do you suggest?
FWIW - I am talking about:

commit 7e1223b50089ab5901215d2fd8c61b42c7cfe034

iwlwifi: mvm: new Alive / error table API

The new API slightly changes the layout of the version of
the firmware - prepare for that.
