Before commit cff959958832 ("mtd: spi-nor: introduce SPI 1-2-2 and SPI
1-4-4 protocols") then we treated 1 as -EINVAL in the caller but after
that commit we changed to propagate the return. My static checker
complains that it's eventually passed to an ERR_PTR() and later
dereferenced, but I'm not totally certain if that's true. Regardless,
returning 1 is wrong.
