This patch fixes the private_flags of mode to be checked and compared against uapi.mode and not from hw.mode. This helps properly trigger modeset at boot if desired by driver.
It helps resolve audio_codec initialization issues if display is connected at boot. Initial discussion on this issue has happened on below thread: https://patchwork.freedesktop.org/series/74828/ v2: No functional change. Fixed the Closes tag and added Maarten's RB. v3: Added Fixes tag.
