0099b7701f KVM: arm/arm64: vgic: Don't flush/sync without a working vgic
If the vgic hasn't been created and initialized, we shouldn't attempt to
look at its data structures or flush/sync anything to the GIC hardware.

This fixes an issue reported by Alexander Graf when using a userspace
irqchip.

6fe407f2d1 KVM: arm64: Require in-kernel irqchip for PMU support
If userspace creates a PMU for the VCPU, but doesn't create an in-kernel
irqchip, then we end up in a nasty path where we try to take an
uninitialized spinlock, which can lead to all sorts of breakages.

Luckily, QEMU always creates the VGIC before the PMU, so we can
establish this as ABI and check for the VGIC in the PMU init stage.
This can be relaxed at a later time if we want to support PMU with a
userspace irqchip.

a56a569818 ASoC: da7219: fix inappropriate condition statement
Sparse reports a below warning.

sound/soc/codecs/da7219.c:804:57: warning: dubious: x & !y

The line includes a condition statement; '(a < b) & !c'. Practically, the
evaluated value of this statement equals to the value of '(a < b) && !c'.
Although, it's not an usual way to use bitwise operations as logical

f2b2f6dcd4 ASoC: stac9766: fix wrong usage of DECLARE_TLV_DB_LINEAR()
As long as reading datasheet of STAC9766/9767, this driver includes wrong
usage of DECLARE_TLV_DB_LINEAR().

In "8.1.2. Master Volume Registers", attenuation of lineout volumes is
represented in 5 bits by -1.5 dB/step from 0 to -46.5 dB. Thus,
'master_tlv' should be dB step representation.

In "8.1.14. Record Gain", gain of volumes is represented in 4 bits by
1.5 dB/step from 0 to 22.5 dB. Thus, 'record_tlv' should be dB step
representation.

In "8.1.5. PC BEEP Volume", attenuation of volume is represented in 4 bits
by -3 dB/step from 0 to 45 dB. Thus, 'beep_tlv' should be dB step
representation.

In "8.1.7. Stereo or Mic Volume" and so on, gain of volumes is represented
in 5 bits by -1.5 dB from 12 to -34.5 dB. Thus, 'mix_tlv' should be dB
step representation.

Totally, current implementation includes misuse of TLV-related macro.

This commit replaces usage of DECLARE_TLV_DB_LINEAR() with
SNDRV_CTL_TLVD_DECLARE_DB_SCALE(), to give proper information to
applications in user land.

7f00ee2bbc brcmfmac: use correct skb freeing helper when deleting flowring
Flowrings contain skbs waiting for transmission that were passed to us
by netif. It means we checked every one of them looking for 802.1x
Ethernet type. When deleting flowring we have to use freeing function
that will check for 802.1x type as well.

Freeing skbs without a proper check was leading to counter not being
properly decreased. This was triggering a WARNING every time
brcmf_netdev_wait_pend8021x was called.

2f0e56fa37 brcmfmac: replace WARNING on timeout with a simple error message
Even with timeout increased to 950 ms we get WARNINGs from time to time.
It mostly happens on A-MPDU stalls (e.g. when station goes out of
range). It may take up to 5-10 secods for the firmware to recover and
for that time it doesn't process packets.

It's still useful to have a message on time out as it may indicate some
firmware problem and incorrect key update. Raising a WARNING however
wasn't really that necessary, it doesn't point to any driver bug anymore
and backtrace wasn't much useful.

c006da0be0 act_ife: Fix false encoding
On ife encode side, the action stores the different tlvs inside the ife
header, where each tlv length field should refer to the length of the
whole tlv (without additional padding) and not just the data length.

On ife decode side, the action iterates over the tlvs in the ife header
and parses them one by one, where in each iteration the current pointer is
advanced according to the tlv size.

Before, the encoding encoded only the data length inside the tlv, which led
to false parsing of ife the header. In addition, due to the fact that the
loop counter was unsigned, it could lead to infinite parsing loop.

This fix changes the loop counter to be signed and fixes the encoding to
take into account the tlv type and size.

On ife encode side, external mac header is copied from the original packet
and may be overridden if the user requests. Before, the mac header copy
was done from memory region that might not be accessible anymore, as
skb_cow_head might free it and copy the packet. This led to random values
in the external mac header once the values were not set by user.

This fix takes the internal mac header from the packet, after the call to
skb_cow_head.

2f38c3c01d ath10k: fix rfc1042 header retrieval in QCA4019 with eth decap mode
Chipset from QCA99X0 onwards (QCA99X0, QCA9984, QCA4019 & future)
rx_hdr_status is not padded to align in 4-byte boundary. Define a
new hw_params field to handle different alignment behaviour between
different hw. This patch fixes improper retrieval of rfc1042 header
with QCA4019. This patch along with "ath10k: Properly remove padding
from the start of rx payload" will fix traffic failure in ethernet
decap mode for QCA4019.

65901a9e70 ath10k: do not check if reset is NULL
Since reset_control_get() never returns NULL, we can use IS_ERR()
instead of IS_ERR_OR_NULL().  The return statements can be simpler
as well.

1190cfdb1a VSOCK: Don't dec ack backlog twice for rejected connections
If a pending socket is marked as rejected, we will decrease the
sk_ack_backlog twice. So don't decrement it for rejected sockets
in vsock_pending_work().

Testing of the rejected socket path was done through code
modifications.

9a54cf462d HID: alps: fix multitouch cursor issue
Issue reproduction procedure:

1. three or more fingers put on Touchpad.
2. release fingers from Touchpad.
3. move the cursor by one finger.
4. the cursor does not move.

Cause:

We do not notify multi fingers state correctly to input subsystem.  For
example, when three fingers release from Touchpad, fingers state is 3 -> 0. It
needs to notify first, second and third finger's releasing state.

Fix this by not breaking out on z axis and move x,y,z input handling
code to the correct place so that it's in fact per-finger.

3783c09eab Merge branch 'bcmgenet-phydev-revert'
Philippe Reynes says:

====================
net: bcmgenet: only use new api ethtool_{get|set}_link_ksettings

Some times ago, a serie of patches were committed :
- commit 62469c7600 ("net: ethernet: bcmgenet: use phydev from struct net_device")
- commit 6b352ebccb ("net: ethernet: broadcom: bcmgenet: use new api ethtool_{get|set}_link_ksettings")
The first patch add a regression on this driver, so it should be reverted.
As the second patch depend on the former, it should be reverted too.

The first patch is buggy because there is a "trick" in this driver.
The structure phydev is kept in the private data when the interface
go down, and used when the interface go up to enable the phy before
the function phy_connect is called.

I don't have this hardware, neither the datasheet. So I won't
update the driver to avoid this trick.

But the real goal of the first serie was to move to the new api
ethtool_{get|set}_link_ksettings. So I provide a new version of
the patch without the "cleaning" of driver to use the phydev
store in the net_device structure.

Changelog:
v3:
- use priv instead of dev (so all the code use the same phydev)
v2:
- use Florian Fainelli patches for the revert instead of Jaedon Shin
- simply use net: bcmgenet: for the prefix of the patch

0299b6acf9 Revert "net: ethernet: bcmgenet: use phydev from struct net_device"
This reverts commit 62469c7600 ("net: ethernet: bcmgenet: use phydev
from struct net_device") because it causes GENETv1/2/3 adapters to
expose the following behavior after an ifconfig down/up sequence:

PING fainelli-linux (10.112.156.244): 56 data bytes
64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.352 ms

64 bytes from 10.112.156.244: seq=1 ttl=61 time=752.448 ms (DUP!)

This was previously fixed by commit 5dbebbb44a ("net: bcmgenet:
Software reset EPHY after power on") but the commit we are reverting was
essentially making this previous commit void, here is why.

Without commit 62469c7600 we would have the following scenario after
an ifconfig down then up sequence:

- bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is
  initialized *before* we get to initialize the UniMAC, this is
  critical to ensure the PHY is in a correct state, priv->phydev is
  valid, this code executes fine

- second time from bcmgenet_mii_probe(), through the normal
  phy_init_hw() call (which arguably could be optimized out)

Everything is fine in that case. With commit 62469c7600, we would have
the following scenario to happen after an ifconfig down then up
sequence:

- bcmgenet_close() calls phy_disonnect() which makes dev->phydev become
  NULL

- when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from
  bcmgenet_power_up() to initialize the internal PHY, the NULL check
  becomes true, so we do not reset the PHY, yet we keep going on and
  initialize the UniMAC, causing MAC activity to occur

- we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is
  too late, the PHY is botched, and causes the above bogus pings/packets
  transmission/reception to occur
