watchdog: cpwd: Fix buffer-overflow
cppcheck-1.47 reports: [drivers/watchdog/cpwd.c:650]: (error) Buffer access out-of-bounds: p.devs The source code is for (i = 0; i < 4; i++) { misc_deregister(&p->devs[i].misc); where devs is defined as WD_NUMDEVS big and WD_NUMDEVS is equal to 3. So the 4 should be a 3 or WD_NUMDEVS. Reported-By: David Binderman Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
