hwrng: n2-drv - 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. The NULL assignment to np->units is removed as there is no interaction between this field and sun4v_hvapi_unregister. Also, the labels out_free_units and out_free are removed as they are no longer required. 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> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
