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

[Alexander Duyck]

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 appear in numerous drivers.

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/>.

Why is this paragraph needed?  The kernel does come with a copy of the
GPL, so it's not an issue for kernel files, right?

thanks,

(IANAL but...) Presumably some people might be concerned about it
because of either patches on mailing lists or otherwise separate from
the kernel, or if someone pulls individual files out of the kernel tree
for another project.

The individual files issue the main concern.  For our driver we have
bits that are often copied out without the rest of the kernel.  User
space drivers are a perfect example.  As a result we find a number of
spots where our driver files are copied and there is no COPYING file.

Thanks,

Alex

Hello Alexander

There is already a checkpatch fsf patch in -next.
Please make patches against that.

cheers, Joe

Subject: [PATCH] checkpatch: update the FSF/GPL address check

The FSF address check is a bit too verbose looking for the GPL text.
Quiet it a bit by requiring --strict for the GPL bit.

Also make the address tests match a few uses of abbreviations for street
names and make it case insensitive.
