* The script "checkpatch.pl" can point information out like the following.
WARNING: Prefer kcalloc over kzalloc with multiply
Thus fix the affected source code places.
* Replace the specification of data types by pointer dereferences
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
