Subject: [PATCH] drm/fbdev: fix drm_fb_helper_deferred_io() build failure
The drm_fb_helper_deferred_io() uses struct fb_deferred_io_pageref,
which isn't available without CONFIG_FB_DEFERRED_IO. Put the function
under corresponding #ifdef to fix build failure if deferred I/O isn't
enabled.
Fixes: 8058944f5226 ("drm/fbdev: Select fbdev I/O helpers from modules that require them")
