In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.

The em28xx driver uses the old-style gpio_request_one() interface to
switch the lna on the PCTV 290E card.
This interface is becoming optional and should no longer be called by
portable drivers. As I could not figure out an obvious replacement,
select the new GPIOLIB_LEGACY symbol as a workaround.

The s5p_mfc_cmd_args structure in the v6 driver is never used, not
initialized to anything other than zero, but as of clang-21 this
causes a warning:
drivers/media/platform/samsung/s5p-mfc/s5p_mfc_cmd_v6.c:45:7: error: variable 'h2r_args' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
45 | &h2r_args);
| ^~~~~~~~
Just remove this for simplicity. Since the function is also called
through a callback, this does require adding a trivial wrapper with
the correct prototype.

Commit 620c266f39 ("fhandle: relax open_by_handle_at() permission
checks") relaxed the coditions for decoding a file handle from non init
userns.
The conditions are that that decoded dentry is accessible from the user
provided mountfd (or to fs root) and that all the ancestors along the
path have a valid id mapping in the userns.
These conditions are intentionally more strict than the condition that
the decoded dentry should be "lookable" by path from the mountfd.
For example, the path /home/amir/dir/subdir is lookable by path from
unpriv userns of user amir, because /home perms is 755, but the owner of
/home does not have a valid id mapping in unpriv userns of user amir.
The current code did not check that the decoded dentry itself has a
valid id mapping in the userns. There is no security risk in that,
because that final open still performs the needed permission checks,
but this is inconsistent with the checks performed on the ancestors,
so the behavior can be a bit confusing.
Add the check for the decoded dentry itself, so that the entire path,
including the last component has a valid id mapping in the userns.

driver implementation had a bug and the polarity information was propagated

Merge tag 'io_uring-6.17-20250828' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
- Use the proper type for min_t() in getting the min of the leftover
bytes and the buffer length.
- As good practice, use READ_ONCE() consistently for reading ring
provided buffer lengths. Additionally, stop looping for incremental
commits if a zero sized buffer is hit, as no further progress can be
made at that point.

In __blk_mq_update_nr_hw_queues() the return value of
blk_mq_sysfs_register_hctxs() is not checked. If sysfs creation for hctx
fails, later changing the number of hw_queues or removing disk will
trigger the following warning:
kernfs: can not remove 'nr_tags', no directory
WARNING: CPU: 2 PID: 637 at fs/kernfs/dir.c:1707 kernfs_remove_by_name_ns+0x13f/0x160

kobjct_del() was called unconditionally even if sysfs creation failed.
Fix it by checkig the kobject creation statusbefore deleting it.
