Subject: [PATCH v2 0/2] drm/vc4: hdmi: Replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Hi everyone,

These patches replace the calls to drm_detect_hdmi_monitor() with the
more efficient drm_display_info.is_hdmi in the VC4 driver.

As I mentioned in v1, vc4_hdmi_encoder.hdmi_monitor (removed by this
series) is used by some code not present in the mainline kernel but
present in the Raspberry Pi tree [1].
Let me know if you want me to open a PR in the Raspberry Pi kernel
project applying this series and fixing this issue.

Thanks,
José Expósito

v1: https://lore.kernel.org/dri-devel/20220406165514.6106-1-jose.exposito89@gmail.com/

v2: Add the ftrace command used in the first patch
    Remove vc4_hdmi_encoder.hdmi_monitor
    (Thanks to Maxime for suggesting these changes)
