-According to the include/linux/watchdog.h WDIOC_SETOPTIONS is
-classified as 'read from device' ioctl call:
-  #define WDIOC_SETOPTIONS        _IOR(WATCHDOG_IOCTL_BASE, 4, int)
-
-However, the driver 'mpcore_wdt' performs 'copy_from_user' only if
-_IOC_WRITE is set, thus the local variable 'uarg' which is used in
-WDIOC_SETOPTIONS handling remains uninitialized.
-
-The proper way to fix this is to bind WDIOC_SETOPTIONS to _IOW,
-but this will break compatibility.
-So adding additional condition for performing 'copy_from_user'.
