There is no need to #define the license of the driver, just put it in
the MODULE_LICENSE() line directly as a text string.
This allows tools that check that the module license matches the source
code license to work properly, as there is no need to unwind the
unneeded dereference.

It's buried in the code comments in include/linux/module.h. One of

a bit more obvious what each should be, but for now, we have lots of
other things to clean up before dealing with this :)
