Subject: [PATCH v2] Staging: unisys: visornic: Use kcalloc instead of kzalloc.

This patch converts kzalloc to kcalloc. The advantage of kcalloc is, 
that will take care of integer overflows which could result from the 
multiplication and it is also nicer to read.

The change was made using Coccinelle.
