drm: rcar-du: Don't leak device_link to CMM

2026-03-26T13:16:25Z

The DU driver creates device_link instances between the DU and CMMs, but never deletes them. Fix it by introducing a rcar_du_cmm structure to group the CMM device and device_link, and deleting the links at cleanup time.

drm: rcar-du: Use __free() to simplify device_node handling

2026-03-26T13:16:24Z

Replace manual of_node_put() calls with __free(). This simplifies error handling code and makes it less bug-prone. Signed-off-by: Laurent Pinchart Link: https://patch.msgid.link/20260323164526.2292491-4-laurent.pinchart+renesas@ideasonboard.com Signed-off-by: Tomi Valkeinen

drm: rcar-du: Store CMM device pointer instead of platform_device

2026-03-26T13:16:24Z

The DU driver stores the CMM devices as pointers to struct platform_device, and passes them to the API exposed by the CMM driver. This is similar to how the VSP is handled, except that the VSP uses struct device pointers. Replace the CMM platform_device pointers with device pointers for consistency.

drm: rcar-du: Ensure correct suspend/resume ordering with VSP

2026-03-26T13:16:24Z

The VSP serves as an interface to memory and a compositor to the DU. It therefore needs to be suspended after and resumed before the DU, to be properly stopped and restarted in a controlled fashion driven by the DU driver. This currently works by chance. Avoid relying on luck by enforcing the correct suspend/resume ordering with device links.

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
