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/display/dc/irq: Remove duplications of hpd_ack function from IRQ

2025-05-13T13:37:09+00:00

The major of dcn and dce irqs share a copy-pasted collection of copy-pasted function, which is: hpd_ack. This patch removes the multiple copy-pasted by moving them to the irq_service.c and make the irq_service's calls the functions implemented by the irq_service.c instead. The hpd_ack function is replaced by hpd0_ack and hpd1_ack, the required constants are also added. The changes were not tested on actual hardware. I am only able to verify that the changes keep the code compileable and do my best to look repeatedly if I am not actually changing any code.

drm/amd/display: Remove useless comparison of unsigned int vs. 0

2024-06-14T20:17:17+00:00

[WHY & HOW] The comparisons of unsigned int with 0 can have no meanings, i.e. unsigned int >= 0 (always true) or unsigned int < 0 (always false), and therefore they are removed. This fixes 12 NO_EFFECT issues reported by Coverity. Reviewed-by: Harry Wentland Acked-by: Zaeem Mohamed Signed-off-by: Alex Hung Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
