The rest of this patch is just cleanup like returning directly instead

drm/exynos: release unhandled page flip events at postclose.
This patch resolves a dead lock issue that could be incurred when
exynos_drm_crtc_dpms function was called.
The exynos_drm_crtc_dpms function waits for the completion of pended
page flip events. However, preclose callback - this releases all unhandled
page flip events - is called prior to the exynos_drm_crtc_dpms function call
when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms
to wait infiniately for the completion of the page flip events.
This patch releases the unhandled page flip events at postclose instead
of preclose so that exynos_drm_crtc_dpms function can be waked up.
Changelog v2:
- fix a memory leak when drm is closed.
. it has a memory leak when a requeste page flip is handled after
drm_events_release() is called and before drm_fb_release()
is called. At this time, a drm_pending_event will not be freed.
So also this chage releases the drm_pending_event at postclose().

The framework hasn't been tied into the DRM core, even though it should

This creates a new display hook called create_connector. The purpose is

This patch removes all of the suspend/resume logic from the individual

number of functions which enable/disable the hardware to just one -- the
dpms callback. This ensures that we always power up/down in a consistent

This patch separates the fimd_activate function into poweron/poweroff
functions to be more consistent with the other drivers in exynos drm. It
also properly cleans up after failures in poweron. The functions have
also been shuffled around such that they are all in the same
spot in the file and poweron/poweroff can be called from the dpms function.

drm/exynos: Disable unused crtc planes from crtc
This patch moves the code which disables unused crtc planes from the
encoder to the crtc. Since there is a 1:1 encoder/crtc mapping in
exynos, the only valid crtc change the pre-existing code could catch is
disconnecting an active crtc from the encoder. Thus it is functionally
equivalent to just disable all planes attached to a crtc when the crtc
is disabled.
