struct i2c_driver::probe_new is about to go away. Switch the driver to
use the probe callback with the same prototype.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.5
A fairly quiet release from a core and framework point of view, but a
very big one from the point of view of new drivers:
- More refectoring from Morimoto-san, this time mainly around DAI
links and how we control the ordering of trigger() callbacks.
- Convert a lot of drivers to use maple tree based caches.
- Lots of work on the x86 driver stack.
- Compressed audio support for Qualcomm.
- Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon,
Ingenic X1000, Intel systems with various CODECs, Longsoon platforms,
Maxim MAX98388, Mediatek MT8188, Nuvoton NAU8825C, NXP platforms with
NAU8822, Qualcomm WSA884x, StarFive JH7110, Texas Instruments TAS2781.

The assignment to variable err is redundant since the code jumps to

Since commit a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag") file
systems can just set the FMODE_CAN_ODIRECT flag at open time instead of
wiring up a dummy direct_IO method to indicate support for direct I/O.
Do that for f2fs so that noop_direct_IO can eventually be removed.

There are several issues in sanity_check_inode():
- The code looks not clean, it checks extra_attr related condition
dispersively.
- It missed to check i_extra_isize w/ lower boundary
- It missed to check feature dependency: prjquota, inode_chksum,
inode_crtime, compression features rely on extra_attr feature.
- It's not necessary to check i_extra_isize due to it will only
be assigned to non-zero value if f2fs_has_extra_attr() is true
in do_read_inode().
Fix them all in this patch.

Versal watchdog driver uses window watchdog mode. Window watchdog
timer(WWDT) contains closed(first) and open(second) window with
32 bit width. Write to the watchdog timer within predefined window
periods of time. This means a period that is not too soon and a
period that is not too late. The WWDT has to be restarted within
the open window time. If software tries to restart WWDT outside of
the open window time period, it generates a reset.

Precompute what is needed to call the access function and do not check the
area's num_accesses again as the pointer may not be valid anymore. Use a

basic one
Eric Dumazet says:
nf_conntrack_dccp_packet() has an unique:
dh = skb_header_pointer(skb, dataoff, sizeof(_dh), &_dh);
And nothing more is 'pulled' from the packet, depending on the content.
dh->dccph_doff, and/or dh->dccph_x ...)
So dccp_ack_seq() is happily reading stuff past the _dh buffer.
BUG: KASAN: stack-out-of-bounds in nf_conntrack_dccp_packet+0x1134/0x11c0
Read of size 4 at addr ffff000128f66e0c by task syz-executor.2/29371
[..]
Fix this by increasing the stack buffer to also include room for
the extra sequence numbers and all the known dccp packet type headers,
then pull again after the initial validation of the basic header.
While at it, mark packets invalid that lack 48bit sequence bit but
where RFC says the type MUST use them.
Compile tested only.
v2: first skb_header_pointer() now needs to adjust the size to
only pull the generic header. (Eric)
Heads-up: I intend to remove dccp conntrack support later this year.

The `shift` variable which indicates the offset in the string at which
to start matching the pattern is initialized to `bm->patlen - 1`, but it
is not reset when a new block is retrieved. This means the implemen-
tation may start looking at later and later positions in each successive
block and miss occurrences of the pattern at the beginning. E.g.,
consider a HTTP packet held in a non-linear skb, where the HTTP request
line occurs in the second block:
[... 52 bytes of packet headers ...]
GET /bmtest HTTP/1.1\r\nHost: www.example.com\r\n\r\n
and the pattern is "GET /bmtest".
Once the first block comprising the packet headers has been examined,
`shift` will be pointing to somewhere near the end of the block, and so
when the second block is examined the request line at the beginning will
be missed.
Reinitialize the variable for each new block.
