  drm/tegra: sor: Reimplement pad clock

The previous fix for addressing the breakage in vmaster slave
initialization, commit a91d6612 ("ALSA: hda - Fix incorrect TLV
callback check introduced during set_fs() removal"), introduced a new
helper to process over each slave kctl.  However, this helper passes
only the original kctl, not the virtual slave kctl.  As a result,
HD-audio driver (which is the only user so far) couldn't initialize
the slave correctly because it's trying to update the value directly
with the original kctl, not with the mapped kctl.

This patch fixes the situation again by passing both the mapped slaved
and original slave kctls to the function.  Luckily there is a single
caller as of now, so changing the call signature is no big matter.

The helper functions to parse and look for the clock source, selector
and multiplier unit may return the descriptor with a too short length
than required, while there is no sanity check in the caller side.
Add some sanity checks in the parsers, at least, to guarantee the
given descriptor size, for avoiding the potential crashes.

Signed-off-by: Takashi Iwai <tiwai@suse.de>

parse_audio_feature_unit() contains a code dividing potentially with
zero when a malformed FU descriptor is passed.  Although there is
already a sanity check, it checks only the value zero, hence it can
still lead to a zero-division when a value 1 is passed there.

Fix it by correcting the sanity check (and the error message
thereof).

The usb-audio driver may trigger an out-of-bound access at parsing a
malformed selector unit, as it checks the header length only after
evaluating bNrInPins field, which can be already above the given
length.  Fix it by adding the length check beforehand.

Some timer compat ioctls have NULL checks of timer instance with
snd_BUG_ON() that bring up WARN_ON() when the debug option is set.
Actually the condition can be met in the normal situation and it's
confusing and bad to spew kernel warnings with stack trace there.
Let's remove snd_BUG_ON() invocation and replace with the simple
checks.  Also, correct the error code to EBADFD to follow the native
ioctl error handling.

Pull printk updates from Petr Mladek:

 - print the warning about dropped messages on consoles on a separate
   line.   It makes it more legible.

 - one typo fix and small code clean up.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk:
  added new line symbol after warning about dropped messages
  printk: fix typo in printk_safe.c
  printk: simplify no_printk()

commit 3179f620 ("ALSA: core: add .get_time_info") had a side effect
of changing the behaviour of the PCM runtime tstamp.  Prior to this
change tstamp was not updated by snd_pcm_update_hw_ptr0() unless the
hw_ptr had moved, after this change tstamp was always updated.

For an application using alsa-lib, doing snd_pcm_readi() followed by
snd_pcm_status() to estimate the age of the read samples by subtracting
status->avail * [sample rate] from status->tstamp this change degraded
the accuracy of the estimate on devices where the pcm hw does not
provide a granular hw_ptr, e.g., devices using
soc-generic-dmaengine-pcm.c and a dma-engine with residue_granularity
DMA_RESIDUE_GRANULARITY_DESCRIPTOR.  The accuracy of the estimate
depended on the latency between the PCM hw completing a period and the
driver called snd_pcm_period_elapsed() to notify ALSA core, typically
determined by interrupt handling latency.  After the change the accuracy
of the estimate depended on the latency between the PCM hw completing a
period and the application calling snd_pcm_status(), determined by the
scheduling of the application process.  The maximum error of the
estimate is one period length in both cases, but the error average and
variance is smaller when it depends on interrupt latency.

Instead of always updating tstamp, update it only if audio_tstamp
changed.

Johannes Berg says:

====================
A few things:
 * straggler timer conversions from Kees
 * memory leak fix in hwsim
 * fix some fallout from regdb changes if wireless is built-in
 * also free aggregation sessions in startup state when station
   goes away, to avoid crashing the timer

When the function tipc_group_filter_msg() finds that a member event
indicates that the member is leaving the group, it first deletes the
member instance, and then purges the message queue being handled
by the call. But the message queue is an aggregated field in the
just deleted item, leading the purge call to access freed memory.

We fix this by swapping the order of the two actions.

On some systems, when we unsplit a port we need to re-create two ports
instead. On other systems, only one needs to be re-created.

Do not try to create a port if during driver initialization it was
assigned a negative module number, which is invalid.

This avoids the following error during unsplit:
[  941.012478] mlxsw_spectrum 0000:01:00.0: Port 43: Failed to map module

The error is harmless and caused by the fact that a local port is
already mapped to module 0.
