[PATCH 5/9] drm/fb-helper: Separate deferred I/O from shadow buffers

2022-03-03 Thread Thomas Zimmermann
DRM drivers will be able to handle deferred I/O by themselves. So a driver will be able to use deferred I/O without an intermediate shadow buffer. Prepare fbdev emulation by separating shadow buffers and deferred I/O from each other. Signed-off-by: Thomas Zimmermann --- drivers/gpu/drm/drm_fb_h
