Regression in 2.6.21-mm1 (git-input) on Dell D610 laptop

Hello,

My D610 ALPS Glide Point is unresponsive with 2.6.21-mm1 patch.
No problem noticed with 2.6.21.

The culprit seems to be git-input. I have applied 2.6.21-mm1 on top of 2.6.21
and then removed git-input patch. It is ok since then.

>From what i can see, no interrupt is raised from the GlidePoint with git-input
applied. IRQ count 12 does not increase. It is when using the touchpad.

I have also tried to disable the ALPS driver in the .config file. IRQ 12 are
then raised when using the Glide Point. X refuses to start.

Any idea?
