fw_version  0x0f)  16 is repeating twice

Is it good idea to turn above magic into a macro

Elantech Clickpad (pms0) stopped working on current

Synopsis:  Elantech Clickpad (pms0) stopped working on current
Category:  kernel
Environment:
System  : OpenBSD 5.7
Details : OpenBSD 5.7-current (GENERIC.MP) #1046: Fri Jun  5 
13:25:01 MDT 2015
 
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

Architecture: OpenBSD.amd64
Machine : amd64
Description:
When I try to use the touchpad on my noteboot the below messages are
shown in xconsole and dmesg. The mouse pointer does not react anymore to
movements on the touchpad.

Affected devic:
pms0: Elantech Clickpad, version 4, firmware 0x575f03

I first noticed this with the snapshot kernel from May 31. With the kernel
from June 5 it's the same. The touchpad was working fine with the snapshot
from May 23.

How-To-Repeat:
Use an Elantech Clickpad, version 4, firmware 0x575f03 with
snapshot from June 5.

Fix:
Workaround: use snapshot from May 23.

 This was probably caused by pms.c commit r1.61 which enabled touchpad
 support for newer elantech devices using firmware versions 0xX8.
 
 Your device (firmware version 0xX7) was not matched before but matches
 now because of the way the new matching check was written. Can you try this
 diff to see if it restores previous behaviour for your device?


After applying this patch I can use the touchpad again. Thanks!
