of_drm_find_bridge() is deprecated. Move to its replacement of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it is put when done. dw_hdmi->bridge is used only in dw_hdmi_top_thread_irq(), so in order to avoid potential use-after-free ensure the irq is freed before putting the dw_hdmi->bridge reference.
