Subject: drivers/infiniband/hw/qib/qib_init.c: use kmalloc_array_node()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7d50207163414d38e6a706904bd915db145fb8a0;p=openwrt%2Fstaging%2Fblogic.git

drivers/infiniband/hw/qib/qib_init.c: use kmalloc_array_node()

Now that we have a NUMA-aware version of kmalloc_array() we can use it
instead of kmalloc_node() without an overflow check in the size
calculation.
