Documentation for drm_crtc_init_with_planes() in drivers/gpu/drm/drm_crtc.c states: «The crtc structure should not be allocated with devm_kzalloc()». However, in drivers/gpu/drm/stm/ltdc.c the 2nd argument of the function drm_crtc_init_with_planes() is a structure allocated with devm_kzalloc() Also, in drivers/gpu/drm/mediatek/mtk_drm_crtc.c drivers/gpu/drm/hisilicon/kirin/kirin_drm_drv.c drivers/gpu/drm/logicvc/logicvc_crtc.c drivers/gpu/drm/meson/meson_crtc.c drivers/gpu/drm/mxsfb/lcdif_kms.c drivers/gpu/drm/mxsfb/mxsfb_kms.c drivers/gpu/drm/renesas/shmobile/shmob_drm_crtc.c drivers/gpu/drm/rockchip/rockchip_drm_vop.c drivers/gpu/drm/rockchip/rockchip_drm_vop2.c drivers/gpu/drm/sun4i/sun4i_crtc.c drivers/gpu/drm/tegra/dc.c drivers/gpu/drm/tilcdc/tilcdc_crtc.c the 2nd argument of the function drm_crtc_init_with_planes() is a field of the structure allocated with devm_kzalloc() Is it correct or can it lead to any problems? -- Ekaterina Orlova Linux Verification Center, ISPRAS
