drmmode_set_scanout_pixmap(pix) adds drmmod->fb_id through a call to drmmode_xf86crtc_resize(), but on a subsequent drmmode_set_scanout_pixmap(NULL) it would not remove the fb. This keeps the crtc marked as busy, which causes the dgpu to not being able to runtime suspend, after an output attached to the dgpu has been used once. Which causes burning through an additional 10W of power and the laptop to run quite hot. This commit adds the missing remove fb call, allowing the dgpu to runtime suspend after an external monitor has be...
