Subject: Staging: unisys: Use kcalloc instead of kzalloc to allocate array
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5e757bc58d15b9fc7d36bb4fcc6f068489e2d29d;p=deliverable%2Flinux.git

Staging: unisys: Use kcalloc instead of kzalloc to allocate array

The advantage of kcalloc is, that will prevent integer overflows which
could result from the multiplication of number of elements and size and
it is also a bit nicer to read.
