Well, in this case I would even recommend something more meaningful:

"Since its independence from Toshiba Group, Toshiba memory Co has become Kioxia Co"

Also, please update the version of your patch to "v3" in the title
"[PATCH v3] ...", this can be done automatically when formatting your
patch with git format-patch with the -v 3 option.

Also the prefix should be "mtd: spinand: toshiba:"

Thanks,
