drm_framebuffer_cleanup - remove a framebuffer object
2. SYNOPSIS ▲
void drm_framebuffer_cleanup(struct drm_framebuffer * fb );
3. ARGUMENTS ▲
framebuffer to remove
4. DESCRIPTION ▲
Cleanup references to a user-created framebuffer. This function is intended to be used from the drivers ->destroy callback.
Note that this function does not remove the fb from active usuage - if it is still used anywhere, hilarity can ensue since userspace could call getfb on the id and get back -EINVAL. Obviously no concern at driver unload time.
Also, the framebuffer will not be removed from the lookup idr - for user-created framebuffers this will happen in in the rmfb ioctl. For driver-private objects (e.g. for fbdev) drivers need to explicitly call drm_framebuffer_unregister_private.
