ieee802154: Introduce the use of the managed version of kzalloc
This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. An explicit linux/device.h include is added to make sure the devm_*() routine declarations are unambiguously available. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
