Pull sound fixes from Takashi Iwai:
 "As a usual pattern, we've got relatively large updates at rc5:

   - A fix for races in ALSA control user elements

   - ASoC DAPM regression due to component refactoring

   - A fix in error handling of ASoC iteration macro

   - ASoC Intel SST Skylake kconfig fix; a new Kconfig will appear as a
     consequence, but in the end it's a good cleanup

   - HD-audio and USB-audio quirks as always

   - Assort of ASoC driver fixes (pcm186x, Intel cht, rockchip, pcm3060,
     rsnd, omap, wm_adsp, qcom, sunxi, stm32)"

+Allocating XArrays
+------------------

+If you use :c:func:`DEFINE_XARRAY_ALLOC` to define the XArray, or
+initialise it by passing ``XA_FLAGS_ALLOC`` to :c:func:`xa_init_flags`,
+the XArray changes to track whether entries are in use or not.
 
 You can call :c:func:`xa_alloc` to store the entry at any unused index
 in the XArray.  If you need to modify the array from interrupt context,
 you can use :c:func:`xa_alloc_bh` or :c:func:`xa_alloc_irq` to disable
-interrupts while allocating the ID.  Unlike :c:func:`xa_store`, allocating
-a ``NULL`` pointer does not delete an entry.  Instead it reserves an
-entry like :c:func:`xa_reserve` and you can release it using either
-:c:func:`xa_erase` or :c:func:`xa_release`.  To use ID assignment, the
-XArray must be defined with :c:func:`DEFINE_XARRAY_ALLOC`, or initialised
-by passing ``XA_FLAGS_ALLOC`` to :c:func:`xa_init_flags`,
+interrupts while allocating the ID.
+
+Using :c:func:`xa_store`, :c:func:`xa_cmpxchg` or :c:func:`xa_insert`
+will mark the entry as being allocated.  Unlike a normal XArray, storing
+``NULL`` will mark the entry as being in use, like :c:func:`xa_reserve`.
+To free an entry, use :c:func:`xa_erase` (or :c:func:`xa_release` if
+you only want to free the entry if it's ``NULL``).
+
+You cannot use ``XA_MARK_0`` with an allocating XArray as this mark
+is used to track whether an entry is free or not.  The other marks are
