Hi, this is your Linux kernel regression tracker.

Well, if I got this right the situation is like this: your change
ac5408991ea6 ("Input: synaptics - switch touchpad on HP Laptop
15-da3001TU to RMI mode") breaks things for some users and hence will be
reverted per the "no regressions rule" ( ).

To get this reapplied someone needs to work with those people that are
affected by the regression to ensure this continue working if the
touchpad is in RMI mode (maybe it depends on the BIOS, the revsition,
the kernel config, or something else). IOW: a better change is needed
that doesn't break things for others. If that's not possible maybe there
is some other solution for you. Is there maybe a kernel parameter you
can apply to switch the device to RMI mode on your machine?

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

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
