ste_dma40: Replace four kzalloc() calls by kcalloc() in d40_hw_detect_init()
* 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.
