Hi, Thorsten here, the Linux kernel's regression tracker.

I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developer don't keep an eye on it, I decided to forward it by
mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=217182 :

See the ticket for more details.


[TLDR for the rest of this mail: I'm adding this report to the list of
tracked Linux kernel regressions; the text you find below is based on a
few templates paragraphs you might have encountered already in similar
form.]

BTW, let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:

#regzbot introduced: v6.1..v6.2
https://bugzilla.kernel.org/show_bug.cgi?id=217182
#regzbot title: input: alps: Dell Latitude E7450 Trackpoint acting up
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (e.g. the buzgzilla ticket and maybe this mail as well, if
this thread sees some discussion). See page linked in footer for details.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

FWIW, another user reported seeing the same problem on a different machine:

```
 Radek 2023-03-14 08:00:31 UTC

I am experiencing the same issue with kernel >6.2.x on Toshiba Z30
with Alps PS/2 DualPoint trackpoint / touchpad. The cursor jumps top
right even with the lowest sensitivity settings. It works just fine
with 6.1 or lower.
```

Pali, or anybody else: anyone any idea what's might be wrong there?
There afaics is only one recent commit to the alps driver (292a089d78d3
("treewide: Convert del_timer*() to timer_shutdown*()")); it it maybe
worth trying to revert it?

[TLDR: This mail in primarily relevant for Linux regression tracking. A
change or fix related to the regression discussed in this thread was
posted or applied, but it did not use a Link: tag to point to the
report, as Linus and the documentation call for. Things happen, no
worries -- but now the regression tracking bot needs to be told manually
about the fix. See link in footer if these mails annoy you.]

Tell regzbot about the fix for this:

#regzbot fix: 754ff5060daf5a1cf4474eff9b4edeb6c17ef7ab
#regzbot ignore-activity
