Alps TouchPad not recognized by kernel

[Andrew]

Expected behavior:
Two-finger scrolling, multi-touch, etc

Actual behavior:
Regular dumb touchpad

Detail:
dmesg|grep ALPS dumps "psmouse serio3: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b3 18"

WORKAROUND: DKMS patching from https://github.com/he1per/psmouse-dkms-alpsv7 . This patch seems to be included in 3.17 onwards, but 3.16 and below I need to DKMS. Perhaps a backport?

Jsalisbury, I did some searching on the kernel git, I *think* it was

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=754ac45745711a7ce0067087e5b55a9c277952ad

I'm not sure if that is the correct commit. It's been in the kernel since 3.13-rc4:

git describe --contains 754ac45745711a7ce0067087e5b55a9c277952ad
v3.13-rc4~42

I'll take a look at the commits in 3.17 and see if any stick out.

We could also perform a "Reverse" bisect to identify the commit.

I think this may be the commit that is needed:

3808843 Input: alps - add support for v7 devices
