Add scripts/coccinelle/alloc/kzalloc-simple.cocci This semantic patch replaces a pair of calls to kmalloc and memset by a single call to kzalloc.

Coccinelle: kzalloc-simple: Add all zero allocating functions There are many instances where memory is allocated using regular allocator functions immediately followed by setting the allocated memory to 0 value using memset. We already have zero memory allocator functions to set the memory to 0 value instead of manually setting it using memset. Therefore, use zero memory allocating functions instead of regular memory allocators followed by memset 0 to remove redundant memset and make the code more cleaner and also reduce the code size.

Coccinelle: remove pci_alloc_consistent semantic to detect in zalloc-simple.cocci Because pci_alloc_consistent has been deprecated. We prefer to use dma_alloc_coherent directly.

coccinelle: add patch rule for dma_alloc_coherent Commit dfd32cad146e ("dma-mapping: remove dma_zalloc_coherent()") removed the definition of dma_zalloc_coherent() and also removed the corresponding patch rule for replacing instances of dma_alloc_coherent + memset in zalloc-simple.cocci (though left the report rule).
