[ Upstream commit3a36273e5a] If no free IBI slot is available, svc_i3c_master_handle_ibi returns immediately. This causes the STOP condition to be missed because the EmitStop request is sent when the transfer is not complete. To resolve this, svc_i3c_master_handle_ibi must wait for the transfer to complete before returning.
