That would be awesome and you are probably a million times faster than
me at that.

There are actually more like 29 locations with such an oddity around AFAIK.

Here is a better, more comprehensive grep:

egrep  "MODULE_LICENSE\([^\"]|DRIVER_LICENSE|DRV_LICENSE|MOD_LICENSE"
-r . | egrep -v
"module\.h|nand_ecc\.c|Documentation|scripts|az6007\.c|mt2063.c"

yielding these:

./drivers/ntb/test/ntb_perf.c:#define DRIVER_LICENSE "Dual BSD/GPL"
./drivers/ntb/test/ntb_perf.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/ntb/test/ntb_tool.c:#define DRIVER_LICENSE "Dual BSD/GPL"
./drivers/ntb/test/ntb_tool.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/ntb/test/ntb_pingpong.c:#define DRIVER_LICENSE "Dual BSD/GPL"
./drivers/ntb/test/ntb_pingpong.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/ntb/ntb.c:#define DRIVER_LICENSE "Dual BSD/GPL"
./drivers/ntb/ntb.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/input/tablet/hanwang.c:#define DRIVER_LICENSE  "GPL"
./drivers/input/tablet/hanwang.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/input/tablet/kbtab.c:#define DRIVER_LICENSE "GPL"
./drivers/input/tablet/kbtab.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/input/tablet/acecad.c:#define DRIVER_LICENSE "GPL"
./drivers/input/tablet/acecad.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/input/misc/keyspan_remote.c:#define DRIVER_LICENSE "GPL"
./drivers/input/misc/keyspan_remote.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/gpu/drm/gma500/psb_drv.h:#define DRIVER_LICENSE "GPL"
./drivers/gpu/drm/gma500/psb_drv.c:MODULE_LICENSE(DRIVER_LICENSE);
./drivers/net/usb/hso.c:#define MOD_LICENSE "GPL"
./drivers/net/usb/hso.c:MODULE_LICENSE(MOD_LICENSE);
./drivers/scsi/csiostor/csio_init.c:MODULE_LICENSE(CSIO_DRV_LICENSE);
./drivers/scsi/csiostor/csio_init.h:#define CSIO_DRV_LICENSE "Dual BSD/GPL"
./drivers/media/usb/usbvision/usbvision-video.c:#define DRIVER_LICENSE "GPL"
