Commit 808a40b69468 ("drm/fbdev-dma: Implement damage handling and deferred I/O") added deferred I/O for fbdev-dma. Also select the Kconfig symbol FB_DEFERRED_IO (via FB_DMAMEM_HELPERS_DEFERRED). Fixes build errors about missing fbdefio, such as
drivers/gpu/drm/drm_fbdev_dma.c:218:26: error: 'struct drm_fb_helper' has no member named 'fbdefio' 218 | fb_helper->fbdefio.delay = HZ / 20; | ^~ drivers/gpu/drm/drm_fbdev_dma.c:219:26: error: 'struct drm_fb_helper' has no member named 'fbdefio' 219 | fb_helper->fbdefio.deferred_io = drm_fb_helper_deferred_io; | ^~ drivers/gpu/drm/drm_fbdev_dma.c:221:21: error: 'struct fb_info' has no member named 'fbdefio' 221 | info->fbdefio = &fb_helper->fbdefio; | ^~ drivers/gpu/drm/drm_fbdev_dma.c:221:43: error: 'struct drm_fb_helper' has no member named 'fbdefio' 221 | info->fbdefio = &fb_helper->fbdefio; | ^~
