AFAIU of_modalias_node will give you "qspi-nor" string. Second
argument passed to the spi_nor_scan is a chip name you expect on the
device. Of course passing "qspi-nor" (if I'm right about
of_modalias_node) doesn't make any sense.
Since my commit
mtd: spi-nor: allow NULL as chip name and try to auto detect it
second argument is optional.
Can you simply pass NULL instead of modalias?
