Subject: [PATCH] drm/exynos: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
Date:   Thu, 16 Jun 2022 15:22:33 +0800

Precedence: bulk

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi.

This driver calls drm_detect_hdmi_monitor() to receive the same
information, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead.
