treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

crypto: keembay - Add missing check after sg_nents_for_len()

2025-08-16T09:22:46+00:00

sg_nents_for_len() returns an int which is negative in case of error. Fixes: 472b04444cd3 ("crypto: keembay - Add Keem Bay OCS HCU driver") Signed-off-by: Thomas Fourier Signed-off-by: Herbert Xu

2025-07-18T10:51:59+00:00

The dma_unmap_sg() functions should be called with the same nents as the dma_map_sg(), not the value the map function returned. Fixes: 472b04444cd3 ("crypto: keembay - Add Keem Bay OCS HCU driver") Signed-off-by: Thomas Fourier Signed-off-by: Herbert Xu

crypto: drivers - Switch back to struct platform_driver::remove()

2024-10-19T00:44:30+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/crypto to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

crypto: intel/keembay-ocs-hcu - Convert to platform remove callback returning void

2023-10-27T10:04:26+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Herbert Xu
