Allocates struct fb_info for a new framebuffer device. Then call drm_fb_helper_single_fb_probe() to create an fbdev screen buffer. Also release the instance on errors by calling drm_fb_helper_release_info(). Simplifies the code and fixes the error cleanup for some of the drivers. Regular release of the struct fb_info instance still happens in drm_fb_helper_fini() as before. v2: - remove error rollback in driver implementations (kernel test robot) - initialize info in TTM implementation (kernel test robot) Signed-off-by: Thomas Zimmermann Acked-by: Christian König # radeon Acked-by: Dmitry Baryshkov # msm Acked-by: Javier Martinez Canillas Link: https://patch.msgid.link/20251027081245.80262-1-tzimmermann@suse.de Stable-dep-of: a18b6e30ecd6 ("drm/tegra: fbdev: Remove offset into framebuffer memory") Signed-off-by: Sasha Levin --- drivers/gpu/drm/armada/armada_fbdev.c | 12 +------ drivers/gpu/drm/drm_fb_helper.c | 41 ++++++++-------------- drivers/gpu/drm/drm_fbdev_dma.c | 12 +------ drivers/gpu/drm/drm_fbdev_generic.c | 12 ++----- drivers/gpu/drm/exynos/exynos_drm_fbdev.c | 9 +---- drivers/gpu/drm/gma500/fbdev.c | 13 +------ drivers/gpu/drm/i915/display/intel_fbdev.c | 9 +---- drivers/gpu/drm/msm/msm_fbdev.c | 9 +---- drivers/gpu/drm/omapdrm/omap_fbdev.c | 9 +---- drivers/gpu/drm/radeon/radeon_fbdev.c | 13 +------ drivers/gpu/drm/tegra/fbdev.c | 9 +---- include/drm/drm_fb_helper.h | 12 ------- 12 files changed, 25 insertions(+), 135 deletions(-) diff --git a/drivers/gpu/drm/armada/armada_fbdev.c b/drivers/gpu/drm/armada/armada_fbdev.c index d223176912b6..e409029638b0 100644 --- a/drivers/gpu/drm/armada/armada_fbdev.c +++ b/drivers/gpu/drm/armada/armada_fbdev.c @@ -43,10 +43,10 @@ static int armada_fbdev_create(struct drm_fb_helper *fbh, struct drm_fb_helper_surface_size *sizes) { struct drm_device *dev = fbh->dev; + struct fb_info *info = fbh->info; struct drm_mode_fb_cmd2 mode; struct armada_framebuffer *dfb; struct armada_gem_object *obj; - struct fb_info *info; int size, ret; void *ptr; @@ -87,12 +87,6 @@ static int armada_fbdev_create(struct drm_fb_helper *fbh, if (IS_ERR(dfb)) return PTR_ERR(dfb); - info = drm_fb_helper_alloc_info(fbh); - if (IS_ERR(info)) { - ret = PTR_ERR(info); - goto err_fballoc; - } - info->fbops = &armada_fb_ops; info->fix.smem_start = obj->phys_addr; info->fix.smem_len = obj->obj.size; @@ -107,10 +101,6 @@ static int armada_fbdev_create(struct drm_fb_helper *fbh, (unsigned long long)obj->phys_addr); return 0; - - err_fballoc: - dfb->fb.funcs->destroy(&dfb->fb); - return ret; } static int armada_fb_probe(struct drm_fb_helper *fbh, diff --git a/drivers/gpu/drm/drm_fb_helper.c b/drivers/gpu/drm/drm_fb_helper.c index 9691c93f19a0..298a8974adad 100644 --- a/drivers/gpu/drm/drm_fb_helper.c +++ b/drivers/gpu/drm/drm_fb_helper.c @@ -499,20 +499,7 @@ int drm_fb_helper_init(struct drm_device *dev, } EXPORT_SYMBOL(drm_fb_helper_init); -/** - * drm_fb_helper_alloc_info - allocate fb_info and some of its members - * @fb_helper: driver-allocated fbdev helper - * - * A helper to alloc fb_info and the member cmap.
