Subject: net: stmmac: Use kcalloc() instead of kmalloc_array()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ec5e5ce1e18b44d0c4779619de3552e0afa5a11d;p=linux.git

net: stmmac: Use kcalloc() instead of kmalloc_array()

We need the memory to be zeroed upon allocation so use kcalloc()
instead.
