I think this Signed-off-by: line from Linu is new in v9. What happened?
I notice that Linu is listed as the driver author:

> +MODULE_DESCRIPTION("Marvell PEM Perf driver");
> +MODULE_AUTHOR("Linu Cherian <lcherian@xxxxxxxxxxx>");

but the patch author is you, so git blame will be inconsistent.

Please can you make sure that MODULE_AUTHOR and the patch author are
consistent, and then use Co-developed-by as well as the additional SoB
for the second author?
