I added '[0-9]\+' at the end of the regex to reduce the number of false
positives...

> drivers/net/can/m_can/m_can.c:#define RXFC_FWM_MASK     (0x7f < RXFC_FWM_SHIFT)
> drivers/usb/gadget/udc/goku_udc.h:#define INT_EPnNAK(n)
> (0x00100 < (n))         /* 0 < n < 4 */

... but you found those two true positives in there. Nice, thanks!
