ASoC: codecs: wcd938x: fix incorrect used of portid
Mixer controls have the channel id in mixer->reg, which is not same
as port id. port id should be derived from chan_info array.
So fix this. Without this, its possible that we could corrupt
struct wcd938x_sdw_priv by accessing port_map array out of range
with channel id instead of port id.

spi: uniphier: Fix a bug that doesn't point to private data correctly
In uniphier_spi_remove(), there is a wrong code to get private data from

This problem was hidden by power domain driver, which call run time resume before it.

2e3dd4a624 usb: common: ulpi: Fix crash in ulpi_match()
Commit 7495af9308 ("ARM: multi_v7_defconfig: Enable drivers for
DragonBoard 410c") enables the CONFIG_PHY_QCOM_USB_HS for the ARM
multi_v7_defconfig. Enabling this Kconfig is causing the kernel to crash
on the Tegra20 Ventana platform in the ulpi_match() function.

The Qualcomm USB HS PHY driver that is enabled by CONFIG_PHY_QCOM_USB_HS,
registers a ulpi_driver but this driver does not provide an 'id_table',
so when ulpi_match() is called on the Tegra20 Ventana platform, it
crashes when attempting to deference the id_table pointer which is not
valid. The Qualcomm USB HS PHY driver uses device-tree for matching the
ULPI driver with the device and so fix this crash by using device-tree
for matching if the id_table is not valid.

d28b159b2d Merge branch 'stmmac-PCS-modernize'
Russell King says:

====================
net: stmmac/xpcs: modernise PCS support

This series updates xpcs and stmmac for the recent changes to phylink
to better support split PCS and to get rid of private MAC validation
functions.

This series is slightly more involved than other conversions as stmmac
has already had optional proper split PCS support.

The first six patches of this series were originally posted on 16th
December for CFT, and Wong Vee Khee reported his Intel Elkhart Lake
setup was fine the first six these. However, no tested-by was given.

The patches:

1) Provide a function to query the xpcs for the interface modes that
   are supported.

2) Populates the MAC capabilities and switches stmmac_validate() to use
   phylink_get_linkmodes(). We do not use phylink_generic_validate() yet
   as (a) we do not always have the supported interfaces populated, and
   (b) the existing code does not restrict based on interface. There
   should be no functional effect from this patch.

3) Populates phylink's supported interfaces from the xpcs when the xpcs
   is configured by firmware and also the firmware configured interface
   mode. Note: this will restrict stmmac to only supporting these
   interfaces modes - stmmac maintainers need to verify that this
   behaviour is acceptable.

4) stmmac_validate() tail-calls xpcs_validate(), but we don't need it to
   now that PCS have their own validation method. Convert stmmac and
   xpcs to use this method instead.

5) xpcs sets the poll field of phylink_pcs to true, meaning xpcs
   requires its status to be polled. There is no need to also set the
   phylink_config.pcs_poll. Remove this.

6) Switch to phylink_generic_validate(). This is probably the most
   contravertial change in this patch set as this will cause the MAC to
   restrict link modes based on the interface mode. From an inspection
   of the xpcs driver, this should be safe, as XPCS only further
   restricts the link modes to a subset of these (whether that is
   correct or not is not an issue I am addressing here.) For
   implementations that do not use xpcs, this is a more open question
   and needs feedback from stmmac maintainers.

7) Convert to use mac_select_pcs() rather than phylink_set_pcs() to set
   the PCS - the intention is to eventually remove phylink_set_pcs()
   once there are no more users of this.

d194923d51 net: stmmac: fill in supported_interfaces
Fill in phylink's supported_interfaces bitmap with the PHY interface
modes which can be used to talk to the PHY.

We indicate that the PHY interface mode passed in platform data is
always supported, as this is the initial mode passed into phylink.
When there is no PCS specified, we assume that this is the only mode
that is supported - indeed, the driver appears not to support dynamic
switching of interface types at present.

When a xpcs is present, it defines the PHY interface modes that the
stmmac driver can support. Request the supported interfaces from the
xpcs driver, and pass them to phylink.

====================
mlxsw: Add RJ45 ports support

We are in the process of qualifying a new system that has RJ45 ports as
opposed to the transceiver modules (e.g., SFP, QSFP) present on all
existing systems.

This patchset adds support for these ports in mlxsw by adding a couple of
missing BaseT link modes and rejecting ethtool operations that are
specific to transceiver modules.

Patchset overview:

Patches #1-#3 are cleanups and preparations.

Patch #4 adds support for two new link modes.

Patches #5-#6 query and cache the port module's type (e.g., QSFP, RJ45)
during initialization.

Patches #7-#9 forbid ethtool operations that are invalid on RJ45 ports.

615ebb8cc4 mlxsw: core_env: Forbid getting module EEPROM on RJ45 ports
MCIA (Management Cable Info Access) register is not supported on RJ45
ports, so getting module EEPROM should be rejected.

Therefore, before trying to access this register, validate the port
module type that was queried during initialization and return an error
to user space in case the port module type is RJ45 (twisted pair).

Examples for output when trying to get EEPROM module:

Using netlink:

 # ethtool -m swp1
 netlink error: mlxsw_core: EEPROM is not equipped on port module type
 netlink error: Invalid argument

Using IOCTL:

 # ethtool -m swp1
 Cannot get module EEPROM information: Invalid argument
 $ dmesg
 mlxsw_spectrum 0000:03:00.0 swp1: EEPROM is not equipped on port module type

c733ebb7cb irqchip/gic-v3-its: Reset each ITS's BASERn register before probe
A recent bug report outlined that the way GICv4.1 is handled across
kexec is pretty bad. We can end-up in a situation where ITSs share
memory (this is the case when SVPET==1) and reprogram the base
registers, creating a situation where ITSs that are part of a given
affinity group see different pointers. Which is illegal. Boo.

In order to restore some sanity, reset the BASERn registers to 0
*before* probing any ITS. Although this isn't optimised at all,
this is only a once-per-boot cost, which shouldn't show up on
anyone's radar.

429c3be8a5 sch_htb: Fail on unsupported parameters when offload is requested
The current implementation of HTB offload doesn't support some
parameters. Instead of ignoring them, actively return the EINVAL error
when they are set to non-defaults.

As this patch goes to stable, the driver API is not changed here. If
future drivers support more offload parameters, the checks can be moved
to the driver side.

Note that the buffer and cbuffer parameters are also not supported, but
the tc userspace tool assigns some default values derived from rate and
ceil, and identifying these defaults in sch_htb would be unreliable, so
they are still ignored.

fc1ca95585 selftests: bpf: Less strict size check in sockopt_sk
Originally, the kernel strictly checked the size of the optval in
getsockopt(TCP_ZEROCOPY_RECEIVE) to be equal to sizeof(struct
tcp_zerocopy_receive). With c8856c0514, this was changed to allow
optvals of different sizes.

The bpf code in the sockopt_sk test was still performing the strict size
check. This fix adapts the kernel behavior from c8856c0514 in the
selftest, i.e., just check if the required fields are there.

5d98fce86e libbpf: deprecate bpf_program__is_<type>() and bpf_program__set_<type>() APIs
Not sure why these APIs were added in the first place instead of
a completely generic (and not requiring constantly adding new APIs with
each new BPF program type) bpf_program__type() and
bpf_program__set_type() APIs. But as it is right now, there are 13 such
specialized is_type/set_type APIs, while latest kernel is already at 30+
BPF program types.

Instead of completing the set of APIs and keep chasing kernel's
bpf_prog_type enum, deprecate existing subset and recommend generic
bpf_program__type() and bpf_program__set_type() APIs.

c5023b8f26 libbpf: deprecate bpf_map__resize()
Deprecated bpf_map__resize() in favor of bpf_map__set_max_entries()
setter. In addition to having a surprising name (users often don't
realize that they need to use bpf_map__resize()), the name also implies
some magic way of resizing BPF map after it is created, which is clearly
not the case.

Another minor annoyance is that bpf_map__resize() disallows 0 value for
max_entries, which in some cases is totally acceptable (e.g., like for
BPF perf buf case to let libbpf auto-create one buffer per each
available CPU core).
