All the SLAVE flow is added but it is not enabled via platform
driver.

I fixed this checkpatch warning for you:

WARNING: quoted string split across lines

Nice, you fooled two code checkers by having code in comments :) No
need to fix, of course:

    SMATCH

    CPPCHECK

Build warning:

I declared the function static to fix it.

Applied to for-next, thanks!
