ASoC: Updates for v4.14

This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers.  Intel and Realtek have been especially active here.

 - Continued work towards moving everything to the component model from
   Morimoto-san.
 - Use of devres for jack detection GPIOs, eliminating some potential
   resource leaks.
 - Jack detection support for Qualcomm MSM8916.
 - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
   systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson
   WM8523.

+ * wait_event_killable_timeout - sleep until a condition gets true or a timeout elapses
+ * @wq_head: the waitqueue to wait on
+ * @condition: a C expression for the event to wait for
+ * @timeout: timeout, in jiffies
+ *
+ * The process is put to sleep (TASK_KILLABLE) until the
+ * @condition evaluates to true or a kill signal is received.
+ * The @condition is checked each time the waitqueue @wq_head is woken up.
+ *
+ * wake_up() has to be called after changing any variable that could
+ * change the result of the wait condition.
+ *
+ * Returns:
+ * 0 if the @condition evaluated to %false after the @timeout elapsed,
+ * 1 if the @condition evaluated to %true after the @timeout elapsed,
+ * the remaining jiffies (at least 1) if the @condition evaluated
+ * to %true before the @timeout elapsed, or -%ERESTARTSYS if it was
+ * interrupted by a kill signal.
+ *
+ * Only kill signals interrupt this process.
