There is a well defined list of expected values for MODULE_LICENSE so warn the user upon usage of unknown values.
Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> ---
Thanks for the review Joe!
"Proprietary" is in the list because this is the full list of "valid" values mentioned in include/linux/module.h. So it's the list of licenses valid for submission, but rather the list of valid values.
Changes since v1: - Fixed nits pointed out by Joe - Added comment to clarify the purpose, as well as origin of the values
