Subject: [PATCH v2] sh_eth: replace devm_kzalloc() with devm_kmalloc_array()
When I was converting the driver to the managed device API, only devm_kzalloc()
was available for memory allocation, so I had to use it, despite zeroing out the
PHY IRQ array right before initializing all its entries to PHY_POLL was quite
stupid. Now that devm_kmalloc_array() has become available, we can avoid the
needless zeroing out...
