This is one of the patches that didn't apply...

...but I don't think this patch is actually necessary. See
spi_nor_scan(), which assigns mtd->dev.parent for us. So as long as the
driver assigns the spi_nor::dev field, the spi-nor framework handles
this for us.

Same comment applies to fsl-quadspi.c (patch 59), which also didn't
apply cleanly. So I don't think we need either of these patches.
