Are you sure that it works? I wouldn't be.
You didn't build this file. Please build your changes before submitting patches.
Furthermore, please always rebase to the current version of the staging tree.
Finally, please use the class modifier "static" as the first keyword of a declaration/definition
as it is done everywhere in the kernel (see "grep -rn "static const" drivers/staging/" and
then switch to "const static" and read the output).
Thanks,
Fabio
