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

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

platform/raspberrypi: Destage VCHIQ MMAL driver

platform/raspberrypi: Destage VCHIQ interface

2025-11-09T02:24:20Z

Destage the VCHIQ interface driver to drivers/platform/raspberrypi. There is still the remaining TODO item of improving the documentation, which can be handled post destaging. Secondly, multimedia drivers like codec and ISP that rely on this interface need to be upstreamed. And lastly, the drivers that facilitate the shared memory between VideoCore and Linux, like the vc-sm-cma driver and vc_mem char driver also need to be upstreamed.

staging: vc04_services: Cleanup VCHIQ TODO entries

2025-11-09T02:24:20Z

Raspberry Pi downstream drivers using VCHIQ have changed a lot since kernel version 4.4 mentioned in the TODO, and are tangential to the destaing process - so drop those items from the list. Secondly, the code indentation for the vchiq interface driver is not so bad anymore since Umang's series (linked below) got merged, so drop it from the TODO.

include: linux: Destage VCHIQ interface headers

2025-11-09T02:24:20Z

Move the VCHIQ headers from drivers/staging/vc04_services/include to include/linux/raspberrypi This is done so that they can be shared between the VCHIQ interface (which is going to be de-staged in a subsequent commit from staging) and the VCHIQ drivers left in the staging/vc04_services (namely bcm2835-audio, bcm2835-camera). The include/linux/raspberrypi/ provides a central location to serve both of these areas.

staging: vc04_services: Drop bcm2835-camera driver

2025-11-09T02:24:20Z

The bcm2835-camera driver is replaced by the V4L2 bcm2835-unicam driver that is already upstream. So drop it from staging. This also simplifies destaging of VCHIQ MMAL, by reducing the users of the MMAL API (this driver is one of them).
