drm/amd/pm: Use str_enabled_disabled in amdgpu_pm sysfs

2026-03-30T18:33:48+00:00

Coccinelle flags hand-rolled "enabled"/"disabled" strings; use the shared str_enabled_disabled() helper from string_choices.h for npm_status and thermal throttling logging sysfs text.

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

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

2026-02-12T20:18:54+00:00

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
