Hi,

First, you need to cc linux-mtd@...ts.infradead.org, make sure to use
the get_maintainer.pl script to get the cc list (you're cc-ing mm
people here, but you should cc mtd folks instead).

This is historical stuff, and does not belong in the commit message,
please move that below the ---.

Also, since you're merely rebasing/fixing a patch authored by ST Lin,
I'd keep the original author and signed off:
Signed-off-by: ST Lin <stlin2@...bond.com>

Thanks!
