Remove include statements for <drm/drm_fb_helper.h> where it is not required (i.e., most of them). In a few places include other header files that are required by the source code. v3: * fix amdgpu include statements * fix rockchip include statements Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221103151446.2638-23-tzimmermann@suse.de
