It should be ok to have your own changes and patches as another compatible license.
The real requirement is that when it’s all together and released if there is gpl code then the bundle license needs to be gpl. But you can have individual changes and patches as MIT license if you want.
It turns out upstream did have the MIT license tucked in there, so it’s not like he added it, it was there. Care to join the discussion in the GitHub issue?

That is correct. IANAL but you can license your patch-set however you want. Only thing is you can’t confuse people which part is which.
