What should be done about this?

Use a driver that isn't a big hack filled with debug code? Such as samsung,s6sy761 from upstream Linux.

Does it make sense to fix? We could just remove the message if it is not impacting any functionality.

The event buffer is empty message is triggered by a bug since the event buffer isn't supposed
to be empty. However since the bug has no real impact so far and the message
is filling up the kernel logs we disable the message.
