Subject: drm/i915: Use kcalloc instead of kzalloc to allocate array
Git-commit: 493dea2876df144ec57a6a9efbe55db43c7a729e
Patch-mainline: v3.4-rc1

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.

The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107
