[PATCH v2] checkpatch: Only flag FSF address, not gnu.org URL

From: Alexander Duyck
Date: Tue Jan 07 2014 - 12:42:39 EST

This change restricts the check for the for the FSF address in the GPL
copyright statement so that it only flags the address, not the references to
the gnu.org/licenses URL which appears to be used in numerous drivers. The
idea is to still allow some reference to an external copy of the GPL in the
event that files are copied out of the kernel tree without the COPYING file.

So for example this statement will still return an error:
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.

However, this statement will not return an error after this patch:
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.

v2: Rebased patch off of linux-next tree.
Updated patch description to include motivation behind change.
