And here too, please change the prefix to "mtd: spi-nor: intel: ".

Thanks,

What Im doing for checking prefix is:
hofrat@debian:~/git/linux-next$ git log --oneline drivers/mtd/spi-nor/intel-spi.c
8afda8b spi-nor: Add support for Intel SPI serial flash controller

is the method of checking the commit prefix with git log --oneline inapropriate ? How would I have found the "mtd: spi-nor: intel:" in this case ?

thx!

It's appropriate, except in this case. You're referring to the commit
introducing a new driver, so this is expected to not find the
'intel:' suffix, but you have 'Add support for Intel SPI serial flash
controller' to clarify the scope.

Regarding the "mtd: " prefix, I think it's better to have it, but
apparently Cyrille is not enforcing that.

> How would I have found the "mtd: spi-nor: intel:" in this case ?

Well, it's a mix of common sense and 'git log --oneline' use :-). Here
you're only modifying the intel driver, but nothing in your subject
mentions it.
