The temporary power up/down of the codec via snd_hda_power_up() and
_down() (or snd_hda_power_up_pm() and _down_pm()) is seen in various
places. This patch introduces simple auto-cleanup macros for those
call patterns, so that the drivers don't have to call the
corresponding power-down calls explicitly.
Namely,
err = snd_hda_power_up(codec);
if (err < 0)
return err;
....
snd_power_down(codec);
can drop the *_down() call by replacing with
CLASS(snd_hda_power, pm)(codec);
if (pm.err < 0)
return pm.err;

The Actiontex MI424WR is a pretty widespread home router, made
in many different revisions.
Revisions A, C and D are based on IXP42x. We add a device tree
for the A/C variant and one for the D variant as these differ in
the location of the WAN PHY on the MDIO bus, and the ethernet
interfaces for the WAN PHY and the DSA switch are switched around.

ASPEED BMC IC has 2 different display engines. Please find AST2600's
datasheet to get detailed information.
1. VGA on PCIe
2. SoC Display (GFX)
By default, video engine (VE) will capture video from VGA. This patch
adds an option to capture video from GFX with standard ioctl,
vidioc_s_input.
An enum, aspeed_video_input, is added for this purpose.
enum aspeed_video_input {
VIDEO_INPUT_VGA = 0,
VIDEO_INPUT_GFX,
VIDEO_INPUT_MAX
};
To test this feature, you will need to enable GFX first. Please refer to
ASPEED's SDK_User_Guide, 6.3.x Soc Display driver, for more information.
In your application, you will need to use v4l2 ioctl, VIDIOC_S_INPUT, as
below to select before start streaming.
int rc;
struct v4l2_input input;
input.index = VIDEO_INPUT_GFX;
rc = ioctl(fd, VIDIOC_S_INPUT, &input);
if (rc < 0)
{
...
}

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.

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.
