[PATCH] drm/framebuffer: Acquire internal references on GEM handles

by Thomas Zimmermann

Acquire GEM handles in drm_framebuffer_init() and release them in the corresponding drm_framebuffer_cleanup(). Ties the handle's lifetime to the framebuffer. Not all GEM buffer objects have GEM handles. If not set, no refcounting takes place. This is the case for some fbdev emulation. This is not a problem as these GEM objects do not use dma-bufs and drivers will not release them while fbdev emulation is running. As all drivers use drm_framebuffer_init(), they will now all hold dma-buf references as fixed in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers"). In the GEM framebuffer helpers, restore the original ref counting on buffer objects. As the helpers for handle refcounting are now no longer called from outside the DRM core, unexport the symbols. Gma500 (unnecessarily) clears the framebuffer's GEM-object pointer before calling drm_framebuffer_cleanup(). Remove these lines to make it consistent with the rest of the drivers. It's one of the fbdev emulations with no GEM handle on their buffers. The change to gma500 is therefore rather cosmetic. Tested on i915, amdgpu (by Bert) and gma500. Also tested on i915 plus udl for the original problem with dma-buf sharing.
