Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Some small SDCA bug fixes reported from various sources. An array bounds
check, an uninitialised variable and some memory allocations that should
zero initialise.

  ASoC: SDCA: Fix off by one error in IRQ bound check
  ASoC: SDCA: Avoid use of uninitialised local name variable
  ASoC: SDCA: Update memory allocations to zero initialise

dd10ed1caf ASoC: convert from clk round_rate() to
Merge series from Brian Masney <bmasney@redhat.com>:

The round_rate() clk ops is deprecated in the clk framework in favor
of the determine_rate() clk ops, so let's go ahead and convert the
drivers in the rtc subsystem using the Coccinelle semantic patch
posted below. I did a few minor cosmetic cleanups of the code in a
few cases.

Coccinelle semantic patch:

bfd291279f ASoC: codec: Convert to GPIO descriptors for
Merge series from Peng Fan <peng.fan@nxp.com>:

This patchset is a pick up of patch 1,2 from [1]. And I also collect
Linus's R-b for patch 2. After this patchset, there is only one user of
of_gpio.h left in sound driver(pxa2xx-ac97).

of_gpio.h is deprecated, update the driver to use GPIO descriptors.

Patch 1 is to drop legacy platform data which in-tree no users are using it
Patch 2 is to convert to GPIO descriptors

Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW
polarity for reset-gpios, so all should work as expected with this patch.

Tidy up a bunch of makefile and Kconfig things, and pull the HID and IRQ

Changes since v1:
 - Don't expose SND_SOC_SDCA to the user
 - Simplify the makefile bits for HID and IRQ

Thanks,
Charles

5f120ccf28 ASoC: set bias_level at if
Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

ASoC has 2 functions to set bias level.

	(A) snd_soc_dapm_force_bias_level()
	(B) snd_soc_dapm_set_bias_level()

(A) sets dapm->bias_level, but (B) is not.
I think we should set it on both (A) and (B).
I think it is miss or bug, but Samsung is the only vendor that feels a
problem about this.

I think this patch (= [1/5]) is correct approach, but some non-samsung
vendor might get affect from this patch-set, so I added [RFC] on this
patch-set.

Furthermore, (B) cares both Card and Component, (A) cares Component only.
I guess it is the reason why it is called as "force" bias_level function.
(A) is used from each drivers, (B) is used from soc-dapm only.
I'm not 100% sure though, except special cases, each driver should use (B),
I guess ?

f40ecc2743 ASoC: soc-dapm: set bias_level if snd_soc_dapm_set_bias_level() was successed
ASoC has 2 functions to set bias level.
	(A) snd_soc_dapm_force_bias_level()
	(B) snd_soc_dapm_set_bias_level()

snd_soc_dapm_force_bias_level() (A) will set dapm->bias_level (a) if
successed.

(A)	int snd_soc_dapm_force_bias_level(...)
	{
		...
		if (ret == 0)
(a)			dapm->bias_level = level;
		...
	}

snd_soc_dapm_set_bias_level() (B) is also a function that sets bias_level.
It will call snd_soc_dapm_force_bias_level() (A) inside, but doesn't
set dapm->bias_level by itself. One note is that (A) might not be called.

(B)	static int snd_soc_dapm_set_bias_level(...)
	{
		...
		ret = snd_soc_card_set_bias_level(...);
		...
		if (dapm != &card->dapm)
(A)			ret = snd_soc_dapm_force_bias_level(...);
		...
		ret = snd_soc_card_set_bias_level_post(...);
		...
	}

dapm->bias_level will be set if (A) was called, but might not be set
if (B) was called, even though it calles set_bias_level() function.

We should set dapm->bias_level if we calls
snd_soc_dapm_set_bias_level() (B), too.

Fixes for a few clk drivers and bindings:

 - Add a missing property to the Mediatek MT8188 clk binding to
   keep binding checks happy

 - Avoid an OOB by setting the correct number of parents in
   dispmix_csr_clk_dev_data

 - Allocate clk_hw structs early in probe to avoid an ordering
   issue where clk_parent_data points to an unallocated clk_hw
   when the child clk is registered before the parent clk in the
   SCMI clk driver

5f02b80c21 Revert "eventpoll: Fix priority inversion problem"
This reverts commit 8c44dac8ad.

I haven't figured out what the actual bug in this commit is, but I did
spend a lot of time chasing it down and eventually succeeded in
bisecting it down to this.

For some reason, this eventpoll commit ends up causing delays and stuck
user space processes, but it only happens on one of my machines, and
only during early boot or during the flurry of initial activity when
logging in.

I must be triggering some very subtle timing issue, but once I figured
out the behavior pattern that made it reasonably reliable to trigger, it
did bisect right to this, and reverting the commit fixes the problem.

Of course, that was only after I had failed at bisecting it several
times, and had flailed around blaming both the drm people and the
netlink people for the odd problems.  The most obvious of which happened
at the time of the first graphical login (the most common symptom being
that some gnome app aborted due to a 30s timeout, often leading to the
whole session then failing if it was some critical component like
gnome-shell or similar).

b44686c839 erofs: fix large fragment handling
Fragments aren't limited by Z_EROFS_PCLUSTER_MAX_DSIZE. However, if
a fragment's logical length is larger than Z_EROFS_PCLUSTER_MAX_DSIZE
but the fragment is not the whole inode, it currently returns
-EOPNOTSUPP because m_flags has the wrong EROFS_MAP_ENCODED flag set.
It is not intended by design but should be rare, as it can only be
reproduced by mkfs with `-Eall-fragments` in a specific case.

Let's normalize fragment m_flags using the new EROFS_MAP_FRAGMENT.

a215b57239 netlink: make sure we allow at least one dump skb
Commit under Fixes tightened up the memory accounting for Netlink
sockets. Looks like the accounting is too strict for some existing
use cases, Marek reported issues with nl80211 / WiFi iw CLI.

To reduce number of iterations Netlink dumps try to allocate
messages based on the size of the buffer passed to previous
recvmsg() calls. If user space uses a larger buffer in recvmsg()
than sk_rcvbuf we will allocate an skb we won't be able to queue.

Make sure we always allow at least one skb to be queued.
Same workaround is already present in netlink_attachskb().
Alternative would be to cap the allocation size to
  rcvbuf - rmem_alloc
but as I said, the workaround is already present in other places.

100c08c89d bnxt_en: Flush FW trace before copying to the coredump
bnxt_fill_drv_seg_record() calls bnxt_dbg_hwrm_log_buffer_flush()
to flush the FW trace buffer.  This needs to be done before we
call bnxt_copy_ctx_mem() to copy the trace data.

Without this fix, the coredump may not contain all the FW
traces.

b74c2a2e9c bnxt_en: Fix DCB ETS validation
In bnxt_ets_validate(), the code incorrectly loops over all possible
traffic classes to check and add the ETS settings.  Fix it to loop
over the configured traffic classes only.

The unconfigured traffic classes will default to TSA_ETS with 0
bandwidth.  Looping over these unconfigured traffic classes may
cause the validation to fail and trigger this error message:

"rejecting ETS config starving a TC\n"

The .ieee_setets() will then fail.
