That found 4 that I think Wolfram's grep missed.

 arch/um/drivers/vector_user.h             |    2 --
 drivers/gpu/drm/mxsfb/mxsfb_regs.h        |    2 --
 drivers/video/fbdev/mxsfb.c               |    2 --
 include/drm/drm_scdc_helper.h             |    3 ---

But it didn't find the two bugs that Geert found where the right side
wasn't a number literal.

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 */
