Currently, an encoder is disabled only when an apply work is queued for the corresponding crtc. This works fine for the paths where userspace explicitly disables crtc, this results in disabling the omapdss device in the crtc's pre_apply function. However, when the omapdrm module is removed, there is no work queued to ensure that the encoder is disabled. This can result in an enabled omapdss device when removing omapdrm. omapdss is left in an inconsistent state, and that prevents us from using that omapdss device being used again. Disable enabled encoders in omap_encoder_destroy, we could consider a better place for doing this later.
