[Freedreno] [PATCH v4 13/13] drm/i915: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Commit a92d083d08b0 created the new flag is_hdmi in drm_display_info
which is set when sink compliant with CEA-861 (EDID) will be treated
as an HDMI sink.

>From that day, this value can be used in some cases instead of
calling drm_detect_hdmi_monitor() and a second parse is avoided
because drm_detect_hdmi_monitor() parses. A TODO task was
registered in Documentation/gpu/todo.rst to perform that task in
the future.

The flag drm_display_info.is_hdmi is set in the function
drm_add_display_info(), which is called from
drm_connector_update_edid_property(). Since commit 5186421cbfe2,
drm_get_edid() calls drm_connector_update_edid_property() when
reading the edid data from an i2c adapter. Therefore, in these
cases drm_display_info.is_hdmi is updated to its correct
value when returning from drm_get_edid().

Replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
in the cases when drm_detect_hdmi_monitor() is called after a
read from an i2c adapter using drm_get_edid() in the i915 driver.
