[PATCH] ntb: remove unneeded DRIVER_LICENSE #defines

[PATCH] ntb: remove unneeded DRIVER_LICENSE #defines

[Greg Kroah-Hartman]

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, especially when the string is defined just a few
lines above the usage of it.
