Subject[PATCH] uwb: Use kcalloc instead of kzalloc to allocate array
From
Date
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
