Applied to github/spi-nor

About patch 1, I wait for Rob's acknowledgement before merging it into
the next branch of github/spi-nor but I'd rather take patch 2 now since
it has been reviewed by Marek and integration issues would be detected
sooner with linux-next so we would have more time to adapt this patch,
if needed.
I've already compile this patch inside the next branch of github/spi-nor
and no warning was risen so I think there should be any issue.

Hence if no integration issue is detected, I'll try to add it into the
next spi-nor PR for 4.12.

Best regards,

Cyrille
