Changelog v3: make exynos_drm_display_power function use exynos_drm_best_encoder function instead of connector->encoder to get a valid encoder. connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB request, connector->encoder is NULL so fix this issue. Changelog v2: remove static prefix so that exynos_drm_best_encoder function could be called by other modules. Changelog v1: this patch fixes the issue that display power callback isn't called. with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL so display_ops->power_on() wouldn't be called so this patch makes exynos_drm_best_encoder function to be used to get a valid encoder of each connector.
