SubjectRe: [PATCH 2/4] MIPS: Loongson64: lemote-2f move ec_kb3310b.h to include dir and clean up To operate EC from platform driver, this head file need able to be include from anywhere. This patch just move ec_kb3310b.h to include dir and clean up ec_kb3310b.h

Some comment as for the previous patch:

Please don't cram the entire commit message into the subject line. The
standard for commit messages to keep lines only so long that when you
look at them in "git log" in a 80 column terminal they don't get line
wrapped or truncated.

When preparing patches for submission please use the git diff option -M
which will make git-diff detect files being moved around and produce a much
smaller, easier to review diff file.
