When drm_helper_disable_unused_functions calls disable function of the CRTC, it also sets the crtc->fb pointer to NULL. This can later (when the mode on that CRTC is setup again from user space) cause ***_do_set_base functions to "think" that there is no old buffer and skip the unpinning code. Consequently, the buffer that has been NULL-ified in drm_helper_disable_unused_functions will never be unpinned causing a leak in VRAM. This patch plugs the leak by unpinning the frame buffer in crtc_disable function.
