The creation of card's id proc file can be moved gracefully into
info.c. Also, the assignment of card->proc_id is superfluous and can
be dropped. So let's do it.
Basically this is no functional change but code refactoring, but one
potential behavior change is that now it returns properly the error
code from snd_info_card_register(), which is a good thing (tm).

For callbacks configuring the state of the components (trigger,
set_params, ack and set_metadata) simplify the code a little and make
intention clearer by aborting as soon as an error is encountered. The
operation has already failed and there is nothing to be gained from
processing the callbacks on additional components. The operations
currently abort after the callbacks, so this simply shortens the
error path.
For callbacks returning information from the driver (copy,
get_metadata, pointer, get_codec_caps, get_caps and get_params)
only look for the first callback provided, currently the code will
call every callback only returning the information provided by the
last. Since we can only return one set of data, it makes no sense to
request the data from every component. Again this just makes the
currently supported feature set a little more clear.

According to the ssm2603 data sheet (control register sequencing), the
digital core should be activated only after all necessary bits in the
power register are enabled, and a delay determined by the decoupling
capacitor on the VMID pin has passed. If the digital core is activated
too early, or even before the ADC is powered up, audible artifacts
appear at the beginning of the recorded signal.
The digital core is also needed for playback, so when recording starts
it may already be enabled. This means we cannot get the power sequence
correct when we want to be able to start recording after playback.
As a workaround put the MIC mute switch into the DAPM routes. This
way we can keep the recording disabled until the MIC Bias has settled
and thus get rid of audible artifacts.

A surprise removal may fail to tear down request queues if it is racing
with the initial asynchronous probe. If that happens, the remove path
won't see the queue resources to tear down, and the controller reset
path may create a new request queue on a removed device, but will not
be able to make forward progress, deadlocking the pci removal.
Protect setting up non-blocking resources from a shutdown by holding the
same mutex, and transition to the CONNECTING state after these resources
are initialized so the probe path may see the dead controller state
before dispatching new IO.

If a controller supports the NS Change Notification, the namespace
scan_work is automatically triggered after attaching a new namespace.
Occasionally the namespace scan_work may append the new namespace to the
list before the admin command effects handling is completed. The effects
handling unfreezes namespaces, but if it unfreezes the newly attached
namespace, its request_queue freeze depth will be off and we'll hit the
warning in blk_mq_unfreeze_queue().
On the next namespace add, we will fail to freeze that queue due to the
previous bad accounting and deadlock waiting for frozen.
Fix that by preventing scan work from altering the namespace list while
command effects handling needs to pair freeze with unfreeze.

The MMC device tree bindings include properties used to signal various
signalling speed modes. Until now the sunxi driver was accepting them
without any further filtering, while the sunxi device trees were not
actually using them.
Since some of the H5 boards can not run at higher speed modes stably,
we are resorting to declaring the higher speed modes per-board.
Regardless, having boards declare modes and blindly following them,
even without proper support in the driver, is generally a bad thing.
Filter out all unsupported modes from the capabilities mask after
the device tree properties have been parsed.

Some H5 boards seem to not have proper trace lengths for eMMC to be able
to use the default setting for the delay chains under HS-DDR mode. These
include the Bananapi M2+ H5 and NanoPi NEO Core2. However the Libre
Computer ALL-H3-CC-H5 works just fine.
For the H5 (at least for now), default to not enabling HS-DDR modes in
the driver, and expect the device tree to signal HS-DDR capability on
boards that work.

Since commit b4935e3a3cfa ("drm/omap: Store bus flags in the
omap_dss_device structure") video mode flags are managed by the omapdss
(and later omapdrm) core based on bus flags stored in omap_dss_device.
This works fine for all devices whose video modes are set by the omapdss
and omapdrm core, but breaks DSI operation as the DSI still uses legacy
code paths and sets the DISPC timings manually.
To fix the problem properly we should move the DSI encoder to the new
encoder model. This will however require a considerable amount of work.
Restore DSI operation by adding back video mode flags handling in the
DSI encoder driver as a hack in the meantime.

When we destroy the interface we already hold the wdev->mtx
while calling cfg80211_pmsr_wdev_down(), which assumes this
isn't true and flushes the worker that takes the lock, thus
leading to a deadlock.
Fix this by refactoring the worker and calling its code in
cfg80211_pmsr_wdev_down() directly.
We still need to flush the work later to make sure it's not
still running and will crash, but it will not do anything.

Disable BCH soft reset according to MX23 erratum #2847 ("BCH soft

problem.
Observed problem: once per 100,000+ MX28 reboots NAND read failed on

[ 4.173846] gpmi_nand: Chip: 0, Error -1
Without BCH soft reset we successfully executed 1,000,000 MX28 reboots.
I have a quote from NXP regarding this problem, from July 18th 2016:
"As the i.MX23 and i.MX28 are of the same generation, they share many
characteristics. Unfortunately, also the erratas may be shared.
In case of the documented erratas and the workarounds, you can also
apply the workaround solution of one device on the other one. This have
been reported, but I’m afraid that there are not an estimated date for
updating the Errata documents.
Please accept our apologies for any inconveniences this may cause."

Certain SNB machines (eg. ASUS K53SV) seem to have a broken BIOS
which misprograms the hardware badly when encountering a suitably
high resolution display. The programmed pipe timings are somewhat
bonkers and the DPLL is totally misprogrammed (P divider == 0).
That will result in atomic commit timeouts as apparently the pipe
is sufficiently stuck to not signal vblank interrupts.
IIRC something like this was also observed on some other SNB
machine years ago (might have been a Dell XPS 8300) but a BIOS
update cured it. Sadly looks like this was never fixed for the
ASUS K53SV as the latest BIOS (K53SV.320 11/11/2011) is still
broken.
The quickest way to deal with this seems to be to shut down
the pipe+ports+DPLL. Unfortunately doing this during the
normal sanitization phase isn't quite soon enough as we
already spew several WARNs about the bogus hardware state.
But it's better than hanging the boot for a few dozen seconds.
Since this is limited to a few old machines it doesn't seem
entirely worthwile to try and rework the readout+sanitization
code to handle it more gracefully.

The ATU port vector contains a bit per port of the switch. The code
wrongly used it as a port number, and incremented a port counter. This
resulted in the wrong interfaces counter being incremented, and
potentially going off the end of the array of ports.
Fix this by using the source port ID for the violation, which really
is a port number.

Make it clear that it is a failure if the cpufreq driver was unable to
register as a cooling device. Makes it easier to find in logs and
grepping for words like fail, err, warn.
