drm/sharp-memory: Do not access GEM-DMA vaddr directly Use DRM's shadow-plane helper to map and access the GEM object's buffer within kernel address space. Encapsulates the vmap logic in the GEM-DMA helpers. The sharp-memory driver currently reads the vaddr field from the GME buffer object directly. This only works because GEM code 'automagically' sets vaddr. Shadow-plane helpers perform the same steps, but with correct abstraction behind drm_gem_vmap(). The shadow-plane state provides the buffer address in kernel address space and the format-conversion state. v2: - fix typo in commit description Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://lore.kernel.org/r/20250627152327.8244-1-tzimmermann@suse.de
