Up to now, once a bridge has been attached to a DRM device, it cannot be undone. In particular you couldn't rmmod/insmod a DRM driver that uses a bridge, because the bridge would remain bound to the first (dead) driver instance. This patch fixes this by introducing drm_encoder_detach() and a ->detach callback in drm_bridge_funcs for the bridge to be notified about detaches. It's DRM/KMS driver responsibility to call drm_encoder_detach(). While adding the bridge detach callback, with its kerneldoc, I also added kerneldoc for attach callback. Few other kerneldocs fixes around there are included.
