Subject: [PATCH 0/4] drm/exynos: misc fixes

Hi Inki,

These four independent patches fixes few problems I have encountered recently.

1st patch is a trivial fix.

2nd patch(kms poll init) fixes old issue, which became more visible after my patch
'drm/exynos: init vblank with real number of crtcs' - driver tried to handle HPD
events even if it was not fully initialized, it caused WARNs and app locks.

Vblank patch is slightly different version of the one proposed in [1]. The only
difference is that it enables vblank after dpms on, it is neccessary because
drm_crtc_vblank_on can call drm_vblank_enable which can call exynos_drm_crtc_enable_vblank
and exynos_drm_crtc_enable_vblank will return error if exynos_crtc->dpms != DRM_MODE_DPMS_ON.

DPMS patch was previously sent as a part of other series, but as the series have been dropped
I have resend it in this patchset.

The patchset is based on exynos-drm-next branch plus following patches:
    drm/exynos: remove explicit encoder/connector de-initialization
    drm/exynos: init vblank with real number of crtcs
    drm/exynos: remove ifdeferry from initialization code

It has been tested on trats board.
