My touchpad MSFT0001:00 04F3:3140 works fine with Kernel 5.11, but stops
working with the new 5.12-rc1
So far I haven't found the cause.

Patch #179 no longer works with kernel 5.10.1, because pinctrl-amd.c has
already been patched with the current kernel version and GLITCH has been
changed.
My touchpad MSFT0001: 00 04F3: 3140 still worked up to 5.10-rc7 with #179.
This is th new code for GLITCH:

We have received feedback in our forum that the touchpad no longer works
after a resuming from suspend.
I've attached the link - maybe you can take a look at it.

Apparently there was a similar problem with the 4.19 kernel, but with
the Intel CPU, which was then solved with the following patch.
https://gitlab.manjaro.org/packages/core/linux419/-/blob/master/ELAN_touchpad_i2c_hid_pinctrl.patch
Now the two lines are included (for example)
See #179 ;-)

The patch is not included in the kernel, as other touchpads will no
longer work.
You can use the attached patch and build your own kernel. It works with

Forget everything up to now - it is a kernel bug that has been known since
January of this year and for which there has been a fix since then.
I can't say why it hasn't been included in the kernel so far.
Here is the patch:

** Changed in: linux (Arch Linux)
Status: Confirmed => Fix Committed

@Coiby Xu (coiby)
You are the best !!!
First of all, thank you very much for the patch - it works perfectly.
All I had to do was add the fix from @wangjun (biggerchina).
Here is the link to the working patch:
@Stillnurs
Please do not confuse apples with oranges!
We're talking about the Lenovo Legion-5 15ARH05 with the MSFT0001: 00 04F3:
3140 touchpad.
It may be nice that it works with the MSFT0001: 01 04F3: 309E on your Legion
Y540, but that is a different hardware and therefore not helpful.
--
Right, it affects all MSFT touchpads.
At the moment there is nothing for MSFT - we will have to be very patient and
hope, that someone can find a driver for it.

"unfortunately using the 'elan touchpad patch' didn't work because
probably MSFT0001:00 04F3:3140 is not an elan device."
Thats not really correct. The touchpad is from Elan (see Vendor-ID 04F3)
and there are the following two versions:
ELAN0001:00 04F3:3140
MSFT0001:00 04F3:3140
The MSFT
The vendor ID is MSFT0001:00 04F3:3140 - therefore the patch cannot work

Just repeat again - the fix works where an incorrect driver is detected.
However, no driver is found at all for the LEGION 5 and the touchpad is
therefore not activated.

I am a Manjaro developer and we have kernels 4.4 / 4.9 / 4.14 / 4.19 / 5.4 /
5.7 / 5.8
The touchpad doesn't work with one of the kernels.
Screen brightness only works with AMD- or nouveau-Driver, not with the
proprietary driver, like 440.100
The brightness display works, but nothing changes.
.
I have found the cause so far that the touchpad MSFT0001: 00 04F3: 3140
is recognized, but no suitable driver is found.
With the touchpad ELAN0001: 00 04F3: 3140 it seems to work with a few tricks.
ELAN is also available in the kernel config, but MSFT is not.
I just don't understand why there
