treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

drm/amd/pm: use sysfs_streq for string matching in amdgpu_pm

2026-02-12T20:18:54Z

The driver uses strncmp() to compare sysfs attribute strings, which does not handle trailing newlines and lacks NULL safety. sysfs_streq() is the recommended function for sysfs string equality checks in the kernel, providing safer and more correct behavior. replace strncmp() with sysfs_streq() in drivers/gpu/drm/amd/pm/amdgpu_pm.c Signed-off-by: Yang Wang Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: Remove power2_average node

2025-11-12T02:54:17Z

SOC power consumption is reported by power1_average. power2_cap_default/min/max only represent second level limits and don't represent a different type of power or power consumption by a subsection of the SOC. Therefore power2_average does not serve any purpose and hence removing power2_average sysfs node Signed-off-by: Asad Kamal Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher
