Changing it to that adds the following 6 new warnings:

./drivers/staging/media/lirc/lirc_zilog.c:806 			    "1) -- please upgrade to a newer driver",
	- bug.

./drivers/staging/rtl8192e/rtl8192e/r8192E_dev.c:529 					 "24G_A[%d] = 0x%x\n", i,
./drivers/staging/rtl8192e/rtl8192e/r8192E_dev.c:537 					 "24G_C[%d] = 0x%x\n", i,
	- the "24G_A" is the last 5 characters of a variable name so
	  this is sloppy code.

./drivers/scsi/pm8001/pm8001_ctl.c:297 			       "0x%08x 0x%08x\n",
./drivers/scsi/pm8001/pm8001_ctl.c:432 			       "0x%08x 0x%08x\n",
./drivers/scsi/qla2xxx/qla_nx2.c:1457 	    "0x%X 0x%X 0x%X 0x%X 0x%X 0x%X\n"
	- hex false positives

I thought about doing that when I wrote my original patch but I was
worried about more hex false positives.  If there are only those 3 then
it's probably not a big deal.  What do you think?
