Wayne Lin 65924ec69b drm/amd/display: Fix wrong handling for AUX_DEFER case ... [Why] We incorrectly ack all bytes get written when the reply actually is defer. When it's defer, means sink is not ready for the request. We should retry the request. [How] Only reply all data get written when receive I2C_ACK|AUX_ACK. Otherwise, reply the number of actual written bytes received from the sink. Add some messages to facilitate debugging as well.
