Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

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

of: Move of_prop_val_eq() next to the single user

2025-03-14T23:01:42+00:00

There's only a single user of of_prop_val_eq(), so move it to overlay.c. This removes one case of exposing struct property outside of the DT code. Signed-off-by: "Rob Herring (Arm)" Link: https://lore.kernel.org/r/20250312212947.1067337-1-robh@kernel.org Signed-off-by: Rob Herring (Arm)

of: Introduce and apply private is_pseudo_property()

2025-02-25T14:43:00+00:00

There are several places which check if a property name is one of 'name'|'phandle'|'linux,phandle'. Introduce and apply private is_pseudo_property() for the check.

of: Constify struct property pointers

2024-10-15T13:58:36+00:00

Most accesses to struct property do not modify it, so constify struct property pointers where ever possible in the DT core code. Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20241010-dt-const-v1-4-87a51f558425@kernel.org Signed-off-by: Rob Herring (Arm)

Functions which don't change the refcount or otherwise modify struct device_node can make struct device_node const. Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20241010-dt-const-v1-3-87a51f558425@kernel.org Signed-off-by: Rob Herring (Arm)

of: Add a helper to free property struct

2024-04-15T13:40:40+00:00

Freeing a property struct is 3 kfree()'s which is duplicated in multiple spots. Add a helper, __of_prop_free(), and replace all the open coded cases in the DT code.
