Subject: [PATCH 3.19 01/75] ASoC: da732x: Fix control-less DAPM routes

3.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@...afoo.de>

commit 8e6a75c102f8e232b599a06e06731d8c5d5f2c5d upstream.

Routes without a control must use NULL for the control name. The da732x
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 da732x driver in the process.

This patch replaces the incorrect "NULL" control name with NULL to fix the
issue.

Fixes: 5fe5b767dc6f ("ASoC: dapm: Do not pretend to support controls for non mixer/mux widgets")
