This patch is not against mainline kernel. There is no support for DTR
mode in kernel yet. Below hunk is not even present in the spi-nor.c.

For future submissions:
Subject line should be one line summary of the patch starting with
prefix "mtd: spi-nor:" (hint: run git log on file to know the format)
and commit message should have detailed description of the patch

Regards
Vignesh
