I have the following mouse:

$ lsusb
...
Bus 002 Device 005: ID 09da:000a A4Tech Co., Ltd. Optical Mouse Opto 510D / 
OP-620D

It was working well till the kernel 5.1.16. I upgraded the kernel to
5.1.18 and the mouse scroll doesn't work any more. The same issue is
with the kernel 5.2.0 and 5.2.1 . I haven't tested it with the 5.1.17
version.

When I compare the kernel .config file from 5.1.16 and 5.1.18, they're
pretty much the same.

I can confirm same issue. Fedora 30, 5.1.17-300.fc30.x86_64 kernel, the
same mouse :

$ lsusb
...
Bus 003 Device 002: ID 09da:000a A4Tech Co., Ltd. Optical Mouse Opto 510D 
/OP-620D

First time I supposed that my mouse is gone, but then I rebooted into
older 5.1.16 kernel - and everything works fine there.

I've been upgraded (F30) into the 5.1.18-300.fc30.x86_64 kernel before a
while, problem still remains. So it has to be something (which occurs)
between 5.1.16 and 5.1.17 and it's not solved yet.

Yes, this patch is working well, as I tested before a while and
confirmed also in RedHat bugzilla there :

This patch fixes the scroll issue for me too.

I'm with fairly old A4Tech X6-005D 
a4tech 0003:09DA:000A.0001: input,hidraw0: USB HID v1.10 Mouse [A4Tech PS/2+USB 
Mouse]

I've tested it on 5.2.1 and 5.2.2.

I hope the patch will make it into 5.2.3.

Could anybody confirm, if this patch is (or isn't yet) included in the
fresh 5.2.4 kernel, please ?

Probably not. You can search for "a4tech" in kernel patch change logs
here: https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.4
(replace the version number at the end of this URL to check out other
versions).

Hmm, probably the same for 5.1.21 :-(. Is here somebody from upstream,
who can say to us, when this patch is planned for (which) stable kernel?
Or explain, why it will not be possible (in the near future) ? I
understand, that sometimes the patch can have more cons than pros, can
be dangerous/broken/whatever, but I guess this is not the case (as we
already confirmed, inserting this patch into 5.1.18 kernel within Fedora
kernel-tree works like a charm, nothing else is affected, etc.). Thanks.

This bug has been filled under Other/Other product/category, so it goes

I opened a new bug into the correct category, but so far it seem to be ignored 
too.
https://bugzilla.kernel.org/show_bug.cgi?id=204347

I guess we need to escalate the things.

The patch has finally made it into linux-5.3-rc4

Maybe soon it will trickle down to older kernel patches.

The fix is in kernel 5.2.11 .

I don't think they would be releasing any more revisions of linux-5.1.x ,
so I consider the bug fixed.
