With that fixed, and the md5sum above:

root@bletchley:~# md5sum /sys/devices/platform/ahb/1e620000.spi/spi_master/spi0/spi0.0/spi-nor/sfdp
a7b9dbf76e99a33db99e557b6676588a  /sys/devices/platform/ahb/1e620000.spi/spi_master/spi0/spi0.0/spi-nor/sfdp

Is it required in commit message, if yes, I will update it.
