Subject: [PATCH v2 net-next 03/12] ionic: use kcalloc for new arrays

Use kcalloc for allocating arrays of structures.

Following along after
commit e71642009cbdA ("ionic_lif: Use devm_kcalloc() in ionic_qcq_alloc()")
there are a couple more array allocations that can be converted
to using devm_kcalloc().
