Actually, no.

I did apply it to a local branch for testing, and I forgot about b4
picking it up. So these patches never reached linux-mtd (hence the "no
commit" lines below each commit).

There are two ways forward:
- We consider the whole series for mtd/fixes (which I will likely send
  next week) and I take v1.
- We keep the series for spi-nor/next and I let someone else apply it
  there.

Thanks,
