ASoC: soc-pcm: use GFP_KERNEL when the code is sleepable
At the kzalloc() call in dpcm_be_connect(), there is no spin lock involved.
It's merely protected by card->pcm_mutex, instead.  The spinlock is applied
at the later call with snd_soc_pcm_stream_lock_irq() only for the list
manipulations.  (See it's *_irq(), not *_irqsave(); that means the context
being sleepable at that point.)  So, we can use GFP_KERNEL safely there.

This patch revert commit d8a9c6e1f6 ("ASoC: soc-pcm: use GFP_ATOMIC for
dpcm structure") which is no longer needed since commit b7898396f4
("ASoC: soc-pcm: Fix and cleanup DPCM locking").

codecs: rt5682s: fix an incorrect NULL check on list iterator
The bug is here:
            if (!dai) {

The list iterator value 'dai' will *always* be set and non-NULL
by for_each_component_dais(), so it is incorrect to assume that
the iterator value will be NULL if the list is empty or no element
is found (In fact, it will be a bogus pointer to an invalid struct
object containing the HEAD). Otherwise it will bypass the check
'if (!dai) {' (never call dev_err() and never return -ENODEV;)
and lead to invalid memory access lately when calling
'rt5682s_set_bclk1_ratio(dai, factor);'.

To fix the bug, just return rt5682s_set_bclk1_ratio(dai, factor);
when found the 'dai', otherwise dev_err() and return -ENODEV;

ASoC: atmel: Remove system clock tree configuration for at91sam9g20ek
The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the
PCK0 output of the SoC, intended in the reference software to be supplied
using PLLB and programmed to 12MHz. As originally written for use with a
board file the audio driver was responsible for configuring the entire tree
but in the conversion to the common clock framework the registration of
the named pck0 and pllb clocks was removed so the driver has failed to
instantiate ever since.

Since the WM8731 driver has had support for managing a MCLK provided via
the common clock framework for some time we can simply drop all the clock
management code from the machine driver other than configuration of the
sysclk rate, the CODEC driver still respects that configuration from the
machine driver.

fba2689ee7 Merge branch 'remove-h8300' of git://git.infradead.org/users/hch/misc into asm-generic
* 'remove-h8300' of git://git.infradead.org/users/hch/misc:
  remove the h8300 architecture

This is clearly the least actively maintained architecture we have at
the moment, and probably the least useful. It is now the only one that
does not support MMUs at all, and most of the boards only support 4MB
of RAM, out of which the defconfig kernel needs more than half just
for .text/.data.

Guenter Roeck did the original patch to remove the architecture in 2013
after it had already been obsolete for a while, and Yoshinori Sato brought
it back in a much more modern form in 2015. Looking at the git history
since the reinstantiation, it's clear that almost all commits in the tree
are build fixes or cross-architecture cleanups:

5467801f1f gpio: Restrict usage of GPIO chip irq members before initialization
GPIO chip irq members are exposed before they could be completely
initialized and this leads to race conditions.

One such issue was observed for the gc->irq.domain variable which
was accessed through the I2C interface in gpiochip_to_irq() before
it could be initialized by gpiochip_add_irqchip(). This resulted in
Kernel NULL pointer dereference.

Following are the logs for reference :-

kernel: Call Trace:
kernel:  gpiod_to_irq+0x53/0x70
kernel:  acpi_dev_gpio_irq_get_by+0x113/0x1f0
kernel:  i2c_acpi_get_irq+0xc0/0xd0
kernel:  i2c_device_probe+0x28a/0x2a0
kernel:  really_probe+0xf2/0x460
kernel: RIP: 0010:gpiochip_to_irq+0x47/0xc0

To avoid such scenarios, restrict usage of GPIO chip irq members before
they are completely initialized.

====================
bnxt_en: XDP redirect fixes

This series includes 3 fixes related to the XDP redirect code path in
the driver.  The first one adds locking when the number of TX XDP rings
is less than the number of CPUs.  The second one adjusts the maximum MTU
that can support XDP with enough tail room in the buffer.  The 3rd one
fixes a race condition between TX ring shutdown and the XDP redirect path.

27d4073f8d bnxt_en: Prevent XDP redirect from running when stopping TX queue
Add checks in the XDP redirect callback to prevent XDP from running when
the TX ring is undergoing shutdown.

Also remove redundant checks in the XDP redirect callback to validate the
txr and the flag that indicates the ring supports XDP. The modulo
arithmetic on 'tx_nr_rings_xdp' already guarantees the derived TX
ring is an XDP ring.  txr is also guaranteed to be valid after checking
BNXT_STATE_OPEN and within RCU grace period.

facc173cf7 bnxt_en: reserve space inside receive page for skb_shared_info
Insufficient space was being reserved in the page used for packet
reception, so the interface MTU could be set too large to still have
room for the contents of the packet when doing XDP redirect.  This
resulted in the following message when redirecting a packet between
3520 and 3822 bytes with an MTU of 3822:

20921c0c86 qed: fix ethtool register dump
To fix a coverity complain, commit d5ac07dfbd
("qed: Initialize debug string array") removed "sw-platform"
(one of the common global parameters) from the dump as this
was used in the dump with an uninitialized string, however
it did not reduce the number of common global parameters
which caused the incorrect (unable to parse) register dump

this patch fixes it with reducing NUM_COMMON_GLOBAL_PARAMS
bye one.

====================
net: phy: micrel: Remove latencies support lan8814

Remove the latencies support both from the PHY driver and from the DT.
The IP already has some default latencies values which can be used to get
decent results. It has the following values(defined in ns):
rx-1000mbit: 429
tx-1000mbit: 201
rx-100mbit:  2346
tx-100mbit:  705

v0->v1:
- fix the split of the patches, there was a compiling error between patch 2 and
  patch 3.

---
But to get better results the following values needs to be set:
rx-1000mbit: 459
tx-1000mbit: 171
rx-100mbit:  1706
tx-100mbit:  1345

We are proposing to use ethtool to set these latencies, the RFC can be found
here[1]

76e9ccd689 net: phy: micrel: Remove DT option lan8814,ignore-ts
When the PHY and the MAC are capable of doing timestamping, the PHY has
priority. Therefore the DT option lan8814,ignore-ts was added such that
the PHY will not expose a PHC so then the timestamping was done in the
MAC. This is not the correct approach of doing it, therefore remove
this.

08ebf903af mmc: core: Fixup support for writeback-cache for eMMC and SD
During the card initialization process, the mmc core checks whether the
eMMC/SD card supports an internal writeback-cache and then enables it
inside the card.

Unfortunately, this isn't according to what the mmc core reports to the
upper block layer. Instead, the writeback-cache support with REQ_FLUSH and
REQ_FUA, are being enabled depending on whether the host supports the CMD23
(MMC_CAP_CMD23) and whether an eMMC supports the reliable-write command.

This is wrong and it may also sound awkward. In fact, it's a remnant
from when both eMMC/SD cards didn't have dedicated commands/support to
control the internal writeback-cache. In other words, it was the best we
could do at that point in time.

To fix the problem, but also without breaking backwards compatibility,
let's align the REQ_FLUSH support with whether the writeback-cache became
successfully enabled - for both eMMC and SD cards.

5d43593337 mmc: block: Check for errors after write on SPI
Introduce a SEND_STATUS check for writes through SPI to not mark
an unsuccessful write as successful.

Since SPI SD/MMC does not have states, after a write, the card will
just hold the line LOW until it is ready again. The driver marks the
write therefore as completed as soon as it reads something other than
all zeroes.
The driver does not distinguish from a card no longer signalling busy
and it being disconnected (and the line being pulled-up by the host).
This lead to writes being marked as successful when disconnecting
a busy card.
Now the card is ensured to be still connected by an additional CMD13,
just like non-SPI is ensured to go back to TRAN state.

While at it and since we already poll for the post-write status anyway,
we might as well check for SPIs error bits (any of them).

The disconnecting card problem is reproducable for me after continuous
write activity and randomly disconnecting, around every 20-50 tries
on SPI DS for some card.
