Subject: [PATCH v2] drm: Improve the output_poll_changed description

From: zhangzhijie <zhangzhijie@...ngson.cn>

this callback was used by drm_kms_helper_hotplug_event()

V2: (Thanks for Daniel's suggestions)
- remove the FIXME below.since with the drm_client
- infrastructure and the generic fbdev emulation we've
- resolved this all very neatly now.
