Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Presumably since nobody has noticed this for the last 12 years, there is
not anyone actually trying to use this driver so we can just remove this
special walnut code and use the generic header so it builds for all

"... nomux only appeared to fix the issue because the controller
continued working after warm reboots. After more thorough testing from
both warm and cold start, I now believe the entry should be added to
i8042_dmi_reset_table rather than i8042_dmi_nomux_table as i8042.reset=1

i8042.nomux is not."

The Acer Aspire 5738z has a button to disable (and re-enable) the
touchpad next to the touchpad.
When this button is pressed a LED underneath indicates that the touchpad
is disabled (and an event is send to userspace and GNOME shows its
touchpad enabled / disable OSD thingie).
So far so good, but after re-enabling the touchpad it no longer works.
The laptop does not have an external ps2 port, so mux mode is not needed
and disabling mux mode fixes the touchpad no longer working after toggling
it off and back on again, so lets add this laptop model to the nomux list.

We don't know when the device will be added with device_add() in
serio_add_port() because serio_add_port() is called from a workqueue
that this driver schedules by calling serio_register_port(). The best we
can know is that the device will definitely not have been added yet when
the start callback is called on the serio device.
While it hasn't been shown to be a problem, proactively move the wakeup
enabling calls to the start hook so that we don't race with the
workqueue calling device_add(). This will avoid racy situations where
code tries to add wakeup sysfs attributes for this device from
dpm_sysfs_add() but the path in device_set_wakeup_capable() has already
done so.

The name of pm_suspend_via_s2idle() is confusing, as it doesn't
reflect the purpose of the function precisely enough and it is
very similar to pm_suspend_via_firmware(), which has a different
purpose, so rename it as pm_suspend_default_s2idle() and update
its only caller, i8042_register_ports(), accordingly.

Instead of signalling wakeup directly from i8042, let psmouse and atkbd
drivers execute basic protocol handling and only then signal wakeup
condition. This solves the issue where we increment wakeup counter
simply because we are getting responses from keyboard/mouse to the
commands we ourselves send to them as part of suspend transition.

Convert string compares of DT node names to use of_node_name_eq helper
instead. For the root node on SUN DT, we need to retrieve the 'name'
property as it is the rare case where the 'name' property and node name
differ. With both changes, it removes direct access to the node name
pointer.
While at it, convert the open coded loop to use for_each_child_of_node().

it's not sufficient to just enable in order to bring the SP core back up.
It seems that the kernel has no business managing this clock. Just let
the firmware keep it enabled.

It makes little sense but still possible to put Hyper-V guests into
suspend-to-idle state. To wake them up two wakeup sources were registered
in the past: hyperv-keyboard and hid-hyperv. However, since
commit eed4d47efe ("ACPI / sleep: Ignore spurious SCI wakeups from
suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch
to pm_wakeup_hard_event() API as these devices are actually the only
possible way to wakeup Hyper-V guests.

"This is the compat_ioctl work related to tty ioctls.
Quite a bit of dead code taken out, all tty-related stuff gone from
fs/compat_ioctl.c. A bunch of compat bugs fixed - some still remain,
but all more or less generic tty-related ioctls should be covered
(remaining issues are in things like driver-private ioctls in a pcmcia
serial card driver not getting properly handled in 32bit processes on
64bit host, etc)"

synclink: reduce pointless checks in ->ioctl()

...
First of all, make it return int. Returning long when native method
had never allowed that is ridiculous and inconvenient.
More importantly, change the caller; if ldisc ->compat_ioctl() is NULL
or returns -ENOIOCTLCMD, tty_compat_ioctl() will try to feed cmd and
compat_ptr(arg) to ldisc's native ->ioctl().
That simplifies ->compat_ioctl() instances quite a bit - they only
need to deal with ioctls that are neither generic tty ones (those
would get shunted off to tty_ioctl()) nor simple compat pointer ones.
Note that something like TCFLSH won't reach ->compat_ioctl(),
even if ldisc ->ioctl() does handle it - it will be recognized
earlier and passed to tty_ioctl() (and ultimately - ldisc ->ioctl()).
For many ldiscs it means that NULL ->compat_ioctl() does the
right thing. Those where it won't serve (see e.g. n_r3964.c) are
also easily dealt with - we need to handle the numeric-argument
ioctls (calling the native instance) and, if such would exist,
the ioctls that need layout conversion, etc.
All in-tree ldiscs dealt with.

Previously, on typical consumer laptops, pressing a key on the keyboard
when the system is in suspend would cause it to wake up (default or
unconditional behaviour). This happens because the EC generates a SCI
interrupt in this scenario.
That is no longer true on modern laptops based on Intel WhiskeyLake,
including Acer Swift SF314-55G, Asus UX333FA, Asus UX433FN and Asus
UX533FD. We confirmed with Asus EC engineers that the "Modern Standby"
design has been modified so that the EC no longer generates a SCI
in this case; the keyboard controller itself should be used for wakeup.
In order to retain the standard behaviour of being able to use the
keyboard to wake up the system, enable serio wakeups by default on
platforms that are using s2idle.

are:

- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around

have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,

Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported

The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g.
VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all
VAIO machines by the nomux blacklist, the data from touch sensor
buttons and touchpad are combined. The protocol used by the buttons is
probably similar to the touchpad protocol (both are Synaptics) so both
devices get enabled. The controller combines the data, creating a mess
which results in random button clicks, touchpad stopping working and
lost sync error messages:
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1

for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

When we probe PS/2 devices we first issue "Get ID" command and only if we
receive what we consider a valid keyboard or mouse ID we disable the device
and continue with protocol detection. That means that the device may be
transmitting motion or keystroke data, while we expect ACK response.
Instead of signaling failure if we see anything but ACK/NAK let's ignore
"garbage" response until we see ACK for the command byte (first byte). The
checks for subsequent ACKs of command parameters will continue be strict.
Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
The devices are allowed to respond to either command byte or command
parameter with a NAK (0xfe), and the host is supposed to resend the
"correct" byte. The device then will either respond with ACK or ERR (0xfc).
Let's teach libps2 to handle the NAK responses properly, so that individual
drivers do not need to handle them.

We do not introduce a new module parameter, but rater rely on the kernel

Instead of using unsigned char for the byte data switch to using u8. Also
use unsigned int for the command codes and timeouts, and have
ps2_handle_ack() and ps2_handle_response() return bool instead of int, as
they do not return error codes but rather signal whether a byte was handled
or not handled. ps2_is_keyboard_id() now returns bool as well.
