I prefer calling _dpu_encoder_phys_cmd_wait_for_idle directly and
optionally adding our own error message. IIRC DRM_ERROR prints source
information such as the function this originated from, and that makes it
impossible to distinguish between the wait_for_tx_complete callback or
the invocation through dpu_encoder_phys_cmd_wait_for_commit_done anyway.
