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/modes: Avoid divide by zero harder in drm_mode_vrefresh()

2024-12-13T22:05:32+00:00

drm_mode_vrefresh() is trying to avoid divide by zero by checking whether htotal or vtotal are zero. But we may still end up with a div-by-zero of vtotal*htotal*...

drm: Add DRM_MODE_TV_MODE_MONOCHROME

2024-06-18T09:13:30+00:00

Add this as a value for enum_drm_connector_tv_mode, represented by the string "Mono", to generate video with no colour encoding or bursts. Define it to have no pedestal (since only NTSC-M calls for a pedestal). Change default mode creation to acommodate the new tv_mode value which comprises both 525-line and 625-line formats.

drm: prefer DRM_MODE_FMT/ARG over drm_mode_debug_printmodeline()

2024-04-15T13:22:50+00:00

We have DRM_MODE_FMT and DRM_MODE_ARG() macros to allow unified debug printing of modes in any printk-formatted logging. Prefer them over drm_mode_debug_printmodeline(). This allows drm device specific logging of modes, in the right drm debug category, and inline with the rest of the logging instead of split to multiple lines.
