coccinelle: add patch rule for dma_alloc_coherent

2020-08-21T20:35:40+00:00

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). Add a new patch rule to remove unnecessary calls to memset after allocating with dma_alloc_coherent. While we're at it, fix a couple of typos.

dma-mapping: remove dma_zalloc_coherent()

2019-01-08T12:58:49+00:00

dma_zalloc_coherent() is no longer needed as it has no users because dma_alloc_coherent() already zeroes out memory for us. The Coccinelle grammar rule that used to check for dma_alloc_coherent() + memset() is modified so that it just tells the user that the memset is not needed anymore.

Coccinelle: remove pci_alloc_consistent semantic to detect in zalloc-simple.cocci

2018-08-22T14:21:43+00:00

Because pci_alloc_consistent has been deprecated. We prefer to use dma_alloc_coherent directly. Therefore, we should remove pci_alloc_consistent to increase the confidence. Acked-by: Julia Lawall Acked-by: Himanshu Jha Signed-off-by: zhong jiang Signed-off-by: Masahiro Yamada

Coccinelle: kzalloc-simple: Rename kzalloc-simple to zalloc-simple

2018-01-16T14:40:17+00:00

Rename kzalloc-simple to zalloc-simple since now the rule is not specific to kzalloc function only, but also to many other zero memory allocating functions specified in the rule. Suggested-by: SF Markus Elfring Signed-off-by: Himanshu Jha Acked-by: Julia Lawall Signed-off-by: Masahiro Yamada
