Routes without a control must use NULL for the control name. The sn95031 driver uses "NULL" instead in a few places. Previous to commit 5fe5b767dc6f ("ASoC: dapm: Do not pretend to support controls for non mixer/mux widgets") the DAPM core silently ignored non-NULL controls on non-mixer and non-mux routes. But starting with that commit it will complain and not add the route breaking the sn95031 driver in the process.
This patch replaces the incorrect "NULL" control name with NULL to fix the issue.
