The saved Cppcheck report flags driver_major:
iscsi-scst/usr/misc.c:44: warning: sscanf() without field width limits
can crash with huge input data. [invalidscanf]
The preceding fgets currently bounds input to a 256-byte buffer, so
this report does not demonstrate an overflow in the present path.
Still, state the 255-character limit in the %s conversion to bind it
directly to devname's capacity, including the terminating NUL.
