Subject: [PATCH v3 0/2] drm/bridge: adv7511: get edid in hpd_work to update
 CEC phys address

This series fixes a small bug where the CEC adapter could have an
invalid CEC address even though we got a hotplug connect and could have
read it.

Changes in v3:
- rebase on latest drm-misc-fixes
- remove redundant NULL check before kfree()
- collect Robert's Reviewed-by
- Link to v2: https://lore.kernel.org/r/20231124-adv7511-cec-edid-v2-0-f0e5eeafdfc2@bang-olufsen.dk

Changes in v2:
- Rearrange driver code to avoid the previous prototype of
  adv7511_get_edid(), per Laurent's feedback
- Free the returned EDID to prevent a memory leak, per Jani's comment
- Link to v1: https://lore.kernel.org/r/20231014-adv7511-cec-edid-v1-1-a58ceae0b57e@bang-olufsen.dk
