Pull pin control fixes from Linus Walleij:
"Some pin control fixes for v6.6 which have been stacking up in my
tree.
Dmitry's fix to some locking in the core is the most substantial, that
was a really neat fix.
The rest is the usual assorted spray of minor driver fixes.
- Drop some minor code causing warnings in the Lantiq driver
- Fix out of bounds write in the Nuvoton driver
- Fix lost IRQs with CONFIG_PM in the Starfive driver
- Fix a locking issue in find_pinctrl()
- Revert a regressive Tegra debug patch
- Fix the Renesas RZN1 pin muxing"
* tag 'pinctrl-v6.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
pinctrl: renesas: rzn1: Enable missing PINMUX
Revert "pinctrl: tegra: Add support to display pin function"
pinctrl: avoid unsafe code pattern in find_pinctrl()
pinctrl: starfive: jh7110: Add system pm ops to save and restore context

rtw89_btc_btf_set_mon_reg
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
Use struct_size() and flex_array_size() helpers to calculate proper sizes
for allocation and memcpy().
Don't change logic at all, and result is identical as before.

There are two kinds of RX packets -- normal and its PPDU status packet.
Both have RX descriptor containing some information such as rate, GI and
bandwidth, and we use these information to find the relationship between
two kinds of packets. Then, we can get more information like RSSI and EVM
from PPDU status packet.

Rework network interface logic. Before this change, the code flow was:
1. Disable interrupt
2. Try to schedule a NAPI
3. Check if it was possible (NAPI is not already scheduled)
4. emit BUG() if we receive interrupt while a NAPI is scheduled
If some application busy poll or set gro_flush_timeout low enough, it's
possible to reach the BUG() condition. Given that the condition may
happen and it wouldn't be a bug, rework the logic to permit such case
and prevent stall with interrupt never enabled again.
Disable the interrupt only if the NAPI can be scheduled (aka it's not
already scheduled) and drop the printk and BUG() call. With these
change, in the event of a NAPI already scheduled, the interrupt is
simply ignored with nothing done.

Now that napi_schedule return a bool, we can drop napi_reschedule that
does the same exact function. The function comes from a very old commit
bfe13f54f502 ("ibm_emac: Convert to use napi_struct independent of struct
net_device") and the purpose is actually deprecated in favour of
different logic.
Convert every user of napi_reschedule to napi_schedule.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
bfa_ioc_get_adapter_manufacturer() simply copies a string literal into
`manufacturer`.
Another implementation of bfa_ioc_get_adapter_manufacturer() from
drivers/scsi/bfa/bfa_ioc.c uses memset + strscpy:
| void
| bfa_ioc_get_adapter_manufacturer(struct bfa_ioc_s *ioc, char *manufacturer)
| {
| memset((void *)manufacturer, 0, BFA_ADAPTER_MFG_NAME_LEN);
| strscpy(manufacturer, BFA_MFG_NAME, BFA_ADAPTER_MFG_NAME_LEN);
| }
Let's use `strscpy_pad` to eliminate some redundant work while still
NUL-terminating and NUL-padding the destination buffer.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect `irqname` to be NUL-terminated based on its use with
of_irq_get_byname() -> of_property_match_string() wherein it is used
with a format string and a `strcmp`:
| pr_debug("comparing %s with %s\n", string, p);
| if (strcmp(string, p) == 0)
| return i; /* Found it; return index */
NUL-padding is not required as is evident by other assignments to
`irqname` which do not NUL-pad:
| if (port->flags & MVPP2_F_DT_COMPAT)
| snprintf(irqname, sizeof(irqname), "tx-cpu%d", i);
| else
| snprintf(irqname, sizeof(irqname), "hif%d", i);
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We can see that linfo->lmac_type is expected to be NUL-terminated based
on the `... - 1`'s present in the current code. Presumably making room
for a NUL-byte at the end of the buffer.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
Let's also prefer the more idiomatic strscpy usage of (dest, src,
sizeof(dest)) rather than (dest, src, SOME_LEN).

Currently hns3 driver supports vf fault detect feature. Several ras caused
by VF resources don't need to do PF function reset for recovery. The driver
only needs to reset the specified VF.
So this patch adds process in ras module. New process will get detailed
information about ras and do the most correct measures based on these
accurate information.

When there are CT table entries, and you rmmod nfp, the following
events can happen:
task1:
nfp_net_pci_remove
↓
nfp_flower_stop->(asynchronous)tcf_ct_flow_table_cleanup_work(3)
↓
nfp_zone_table_entry_destroy(1)
task2:
nfp_fl_ct_handle_nft_flow(2)
When the execution order is (1)->(2)->(3), it will crash. Therefore, in
the function nfp_fl_ct_del_flow, nf_flow_table_offload_del_cb needs to
be executed synchronously.
At the same time, in order to solve the deadlock problem and the problem
of rtnl_lock sometimes failing, replace rtnl_lock with the private
nfp_fl_lock.

use struct_size()
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
Also, relocate `event->datalen = datalen;` to before calling
`memcpy(event->data, data, datalen);`, so that the __counted_by
annotation has effect, and flex-array member `data` can be properly
bounds-checked at run-time.
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and

Add phylink capabilities for vsc73xx. Although this switch driver does
populates the .adjust_link method, dsa_slave_phy_setup() will still be
used to create phylink instances for the LAN ports, although phylink
won't be used for shared links.
There are two different classes of switch - 5+1 and 8 port. The 5+1
port switches uses port indicies 0-4 for the user interfaces and 6 for
the CPU port. The 8 port is confusing - some comments in the driver
imply that port index 7 is used, but the driver actually still uses 6,
so that is what we go with. Also, there appear to be no DTs in the
kernel tree that are using the 8 port variety.
It also looks like port 5 is always skipped.
The switch supports 10M, 100M and 1G speeds. It is not clear whether
all these speeds are supported on the CPU interface. It also looks like
symmetric pause is supported, whether asymmetric pause is as well is
unclear. However, it looks like the pause configuration is entirely
static, and doesn't depend on negotiation results.
So, let's do the best effort we can based on the information found in
the driver when creating vsc73xx_phylink_get_caps().

The switch statement in netvsc_send_completion() is incorrectly validating
the length of incoming network packets by falling through to the next case.
Avoid the fallthrough. Instead break after a case match and then process
the complete() call.
The current code has not caused any known failures. But nonetheless, the
code should be corrected as a different ordering of the switch cases might
cause a length check to fail when it should not.

According to the definition of virtqueue coalescing spec[1]:
Upon disabling and re-enabling a transmit virtqueue, the device MUST set
the coalescing parameters of the virtqueue to those configured through the
VIRTIO_NET_CTRL_NOTF_COAL_TX_SET command, or, if the driver did not set
any TX coalescing parameters, to 0.
Upon disabling and re-enabling a receive virtqueue, the device MUST set
the coalescing parameters of the virtqueue to those configured through the
VIRTIO_NET_CTRL_NOTF_COAL_RX_SET command, or, if the driver did not set
any RX coalescing parameters, to 0.
We need to add this setting for vq resize (ethtool -G) where vq_reset happens.

Background:
1. Commit 0c465be183c7 ("virtio_net: ethtool tx napi configuration") uses
tx-frames to toggle napi_tx (0 off and 1 on) if notification coalescing
is not supported.
2. Commit 31c03aef9bc2 ("virtio_net: enable napi_tx by default") enables
napi_tx for all txqs by default.
Status:
When virtio-net supports notification coalescing, after initialization,
tx-frames is 0 and napi_tx is true.
Problem:
When the user only wants to set rx coalescing params using
ethtool -C eth0 rx-usecs 10, or
ethtool -Q eth0 queue_mask 0x1 -C rx-usecs 10,
these cmds will carry tx-frames as 0, causing the napi_tx switching condition
is satisfied. Then the user gets:
netlink error: Device or resource busy.
The same happens when trying to set rx-frames, adaptive_rx, adaptive_tx...
How to fix:
When notification coalescing feature is negotiated, initially make the
value of tx-frames to be consistent with napi_tx.
For compatibility with the past, it is still supported to use tx-frames
to toggle napi_tx.

syzbot has found an uninit-value bug triggered by the dm9601 driver [1].
This error happens because the variable res is not updated if the call
to dm_read_shared_word returns an error. In this particular case -EPROTO
was returned and res stayed uninitialized.
This can be avoided by checking the return value of dm_read_shared_word
and propagating the error if the read operation failed.

Pull xen fix from Juergen Gross:
"A fix for the xen events driver:
Closing of an event channel in the Linux kernel can result in a
deadlock. This happens when the close is being performed in parallel
to an unrelated Xen console action and the handling of a Xen console
interrupt in an unprivileged guest.
The closing of an event channel is e.g. triggered by removal of a
paravirtual device on the other side. As this action will cause
console messages to be issued on the other side quite often, the
chance of triggering the deadlock is not negligible"
