The use of hwmon_device_register_with_groups() is deprecated.
Modified the driver to use hwmon_device_register_with_info().
Driver currently exports only temp1_input through hwmon sysfs
interface. But FW has been modified to report more threshold
temperatures and driver want to report them through the
hwmon interface.

This is in preparation for upcoming patches in the series.
Driver has to expose more threshold temperatures through the
hwmon sysfs interface. More code will be added and do not
want to overload bnxt.c.

Driver currently does hwmon device register and unregister
in open and close() respectively. As a result, user will not
be able to query hwmon temperature when interface is in
ifdown state.
Enhance it by moving the hwmon register/unregister to the
probe/remove functions.

In some OVS environments the TCP pseudo header checksum may need to be
recomputed. Currently this is only done when the interface instance is
configured for "Trunk Mode". We found the issue also occurs in some
Kubernetes environments, these environments do not use "Trunk Mode",
therefor the condition is removed.
Performance tests with this change show only a fractional decrease in
throughput (< 0.2%).

This is not an actual bug because the sscanf() parsing makes sure that
the u8 are only two digits long and the u16 only three digits long.
Thus below declaration:
char buf[max(sizeof("xx.xx.xx"), sizeof("axxx/xxx"))];
allocates just what is needed to represent either of the versions.
This warning was known but ignored because, at the time of writing,
-Wformat-truncation was not present in the kernel, not even at W=3 [2].
One way to silence this warning is to check the range of all sub
version numbers are valid: [0, 99] for u8 and range [0, 999] for u16.
The module already has a logic which considers that when all the sub
version numbers are zero, the version number is not set. Note that not
having access to the device specification, this was an arbitrary
decision. This logic can thus be removed in favor of global check that
would cover both cases:
- the version number is not set (parsing failed)
- the version number is not valid (paranoiac check to please gcc)
Before starting to parse the product info string, set the version
sub-numbers to the maximum unsigned integer thus violating the
definitions of struct es58x_sw_version or struct es58x_hw_revision.
Then, rework the es58x_sw_version_is_set() and
es58x_hw_revision_is_set() functions: remove the check that the
sub-numbers are non zero and replace it by a check that they fit in
the expected number of digits. This done, rename the functions to
reflect the change and rewrite the documentation. While doing so, also
add a description of the return value.
Finally, the previous version only checked that
&es58x_hw_revision.letter was not the null character. Replace this
check by an alphanumeric character check to make sure that we never
return a special character or a non-printable one and update the
documentation of struct es58x_hw_revision accordingly.
All those extra checks are paranoid but have the merit to silence the
newly introduced W=1 format-truncation warning [1].

The k3_udma_glue_tx_get_irq() function currently returns negative error
codes on error, zero on error and positive values for success. This
complicates life for the callers who need to propagate the error code.
Also GCC will not warn about unsigned comparisons when you check:
if (unsigned_irq <= 0)
All the callers have been fixed now but let's just make this easy going
forward.

In the while loop of vringh_iov_xfer(), `partlen` could be 0 if one of
the `iov` has 0 lenght.
In this case, we should skip the iov and go to the next one.
But calling vringh_kiov_advance() with 0 lenght does not cause the
advancement, since it returns immediately if asked to advance by 0 bytes.

blk_mark_disk_dead is the proper interface to shut down a block
device, but it also makes the disk unusable forever.
nbd_clear_sock_ioctl on the other hand wants to shut down the file
system, but allow the block device to be used again when when connected
to another socket. Switch nbd to use disk_force_media_change and
nbd_bdev_reset to go back to a behavior of the old __invalidate_device
call, with the added benefit of incrementing the device generation
as there is no guarantee the old content comes back when the device

upon in the netdev community and explicitly marked as something to avoid
in the Linux coding-style document (section 15).
Even though these functions are only used once, it is expected that GCC

Report the maximum number of IBs that can be pushed with a single
DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM.
While the maximum number of IBs per ring might vary between chipsets,
the kernel will make sure that userspace can only push a fraction of the
maximum number of IBs per ring per job, such that we avoid a situation
where there's only a single job occupying the ring, which could
potentially lead to the ring run dry.
Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs
that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that
all channels of a given device have the same ring size.

devices when registration fails which replaces a half baked fix with a
more complete one which uses the device model release() function
properly.
The other fix is a device specific fix for mt6358, the driver said
that the LDOs supported mode configuration but this is not actually
the case and could cause issues"

of the new register into a bitmask correctly and marking the wrong

This would only have affected devices with a register stride other

There is a potential race condition in amdtee_close_session that may
cause use-after-free in amdtee_open_session. For instance, if a session
has refcount == 1, and one thread tries to free this session via:
kref_put(&sess->refcount, destroy_session);
the reference count will get decremented, and the next step would be to
call destroy_session(). However, if in another thread,
amdtee_open_session() is called before destroy_session() has completed
execution, alloc_session() may return 'sess' that will be freed up
later in destroy_session() leading to use-after-free in
amdtee_open_session.
To fix this issue, treat decrement of sess->refcount and removal of
'sess' from session list in destroy_session() as a critical section, so
that it is executed atomically.

When raid5_get_active_stripe is called with a ctx containing a stripe_head in
its batch_last pointer, it can cause a deadlock if the task sleeps waiting on
another stripe_head to become available. The stripe_head held by batch_last
can be blocking the advancement of other stripe_heads, leading to no
stripe_heads being released so raid5_get_active_stripe waits forever.
Like with the quiesce state handling earlier in the function, batch_last
needs to be released by raid5_get_active_stripe before it waits for another
stripe_head.

The vcap_decode_rule() never returns NULL. There is no need to check
for that. This code assumes that if it did return NULL we should
end abruptly and return success. It is confusing. Fix the check to
just be if (IS_ERR()) instead of if (IS_ERR_OR_NULL()).

This patch adds functions for providing in KSZ9477 switch HSR
(High-availability Seamless Redundancy) hardware offloading.
According to AN3474 application note following features are provided:
- TX packet duplication from host to switch (NETIF_F_HW_HSR_DUP)
- RX packet duplication discarding
- Prevention of packet loop
For last two ones - there is a probability that some packets will not
be filtered in HW (in some special cases - described in AN3474).
Hence, the HSR core code shall be used to discard those not caught frames.
Moreover, some switch registers adjustments are required - like setting
MAC address of HSR network interface.
Additionally, the KSZ9477 switch has been configured to forward frames
between HSR ports (e.g. 1,2) members to provide support for
NETIF_F_HW_HSR_FWD flag.
Join and leave functions are written in a way, that are executed with
single port - i.e. configuration is NOT done only when second HSR port
is configured.

Defining macros which have the same name but different values is bad
practice, because it makes it hard to avoid code duplication. The same
code does different things, depending on the file it's placed in.
Case in point, we want to access REG_SW_MAC_ADDR from ksz_common.c, but
currently we can't, because we don't know which kszXXXX_reg.h to include
from the common code.
Remove the REG_SW_MAC_ADDR_{0..5} macros from ksz8795_reg.h and
ksz9477_reg.h, and re-add this register offset to the dev->info->regs[]
array.

Drivers can provide meaningful error messages which state a reason why
they can't perform an offload, and dsa_slave_changeupper() already has
the infrastructure to propagate these over netlink rather than printing
to the kernel log. So pass the extack argument and modify the xrs700x
driver's port_hsr_join() prototype.
Also take the opportunity and use the extack for the 2 -EOPNOTSUPP cases
from xrs700x_hsr_join().
