SubjectRegression since commit 92bac83
Date
Hi,

I recently upgraded the kernel in a Dell Latitude D600 and found that the
touchpad clicks failed. The problem was bisected to commit
92bac83dd79e60e65c475222e41a992a70434beb ("Input: alps - non interleaved V2
dualpoint has separate stick button bits"). The laptop has a combination
touchpad and control stick. For this device, the following values are found:

priv->protoversion is 0x200 (ALPS_PROTO_V2)
priv->flags is 0x6 (ALPS_DUALPOINT | ALPS_PASS)

As a result, the new code added in this patch is executed, and left, right, and
middle are updated. Once this code is introduced, a left click causes some event
as it will wake a sleeping screen, but not select any windows or do anything useful.

Please advise on what information would be needed to help debug this problem.

Thanks,

Larry
