ASoC: Updates for v4.21 

Not much work on the core this time around but we've seen quite a bit of
 driver work, including on the generic DT drivers.  There's also a large
 part of the diff from a merge of the DaVinci and OMAP directories, along
 with some active development there:
 
  - Preparatory work from Morimoto-san for merging the audio-graph and
    audio-graph-scu cards.
  - A merge of the TI OMAP and DaVinci directories, the OMAP product line
    has been merged into the DaVinci product line so there is now a lot
    of IP sharing which meant that the split directories just got in the
    way.  This has pulled in a few architecture changes as well.
  - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl.
  - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
    RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
    controllers.

The security list is not a disclosure channel. For that, see Coordination

Once a robust fix has been developed, our preference is to release the
fix in a timely fashion, treating it no differently than any of the other
thousands of changes and fixes the Linux kernel project releases every
month.
Once a robust fix has been developed, the release process starts. Fixes
for publicly known bugs are released immediately.
However, at the request of the reporter, we will postpone releasing the
fix for up to 5 business days after the date of the report or after the
embargo has lifted; whichever comes first. The only exception to that
rule is if the bug is publicly known, in which case the preference is to
release the fix as soon as it's available.
Although our preference is to release fixes for publicly undisclosed bugs
as soon as they become available, this may be postponed at the request of
the reporter or an affected party for up to 7 calendar days from the start
of the release process, with an exceptional extension to 14 calendar days
if it is agreed that the criticality of the bug requires more time. The
only valid reason for deferring the publication of a fix is to accommodate
the logistics of QA and large scale rollouts which require release
coordination.
Whilst embargoed information may be shared with trusted individuals in
order to develop a fix, such information will not be published alongside

indices. Storing into one index may result in the entry retrieved by
some, but not all of the other indices changing.
Sometimes you need to ensure that a subsequent call to :c:func:`xa_store`
will not need to allocate memory. The :c:func:`xa_reserve` function
will store a reserved entry at the indicated index. Users of the normal
API will see this entry as containing ``NULL``. If you do not need to
use the reserved entry, you can call :c:func:`xa_release` to remove the
unused entry. If another user has stored to the entry in the meantime,
:c:func:`xa_release` will do nothing; if instead you want the entry to
become ``NULL``, you should use :c:func:`xa_erase`.
If all entries in the array are ``NULL``, the :c:func:`xa_empty` function
will return ``true``.
Finally, you can remove all entries from an XArray by calling
:c:func:`xa_destroy`. If the XArray entries are pointers, you may wish
to free the entries first. You can do this by iterating over all present
entries in the XArray using the :c:func:`xa_for_each` iterator.
ID assignment
-------------
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
available for your use.

- These codes are used for vertical and horizontal scroll wheels,

physical size of which varies by device. For high-resolution wheels (which
report multiple events for each notch of movement, or do not have notches)
this may be an approximation based on the high-resolution scroll events.

@ -1056,18 +1056,23 @@ The kernel interface functions are as follows:
u32 rxrpc_kernel_check_life(struct socket *sock,
struct rxrpc_call *call);
void rxrpc_kernel_probe_life(struct socket *sock,
struct rxrpc_call *call);
This returns a number that is updated when ACKs are received from the peer
(notably including PING RESPONSE ACKs which we can elicit by sending PING
ACKs to see if the call still exists on the server). The caller should
compare the numbers of two calls to see if the call is still alive after
waiting for a suitable interval.
The first function returns a number that is updated when ACKs are received
from the peer (notably including PING RESPONSE ACKs which we can elicit by
sending PING ACKs to see if the call still exists on the server). The
caller should compare the numbers of two calls to see if the call is still
alive after waiting for a suitable interval.
This allows the caller to work out if the server is still contactable and
if the call is still alive on the server whilst waiting for the server to
process a client operation.
This function may transmit a PING ACK.
The second function causes a ping ACK to be transmitted to try to provoke
the peer into responding, which would then cause the value returned by the
first function to change. Note that this must be called in TASK_RUNNING
state.
