Move the calls to drm_fb_helper_alloc_info() from drivers into a single place in fbdev helpers. 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 <tzimmermann@suse.de> Acked-by: Christian König <christian.koenig@amd.com> # radeon Acked-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> # msm Acked-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patch.msgid.link/20251027081245.80262-1-tzimmermann@suse.de
