Subject: [v3] Support Elan Touchscreen eKTF product.

Hi Scott,

Not sure what is happening with the patch - seems to have been sitting 
for quite a while. Is it still being worked on?
I integrated it into our arm/arch-vt8500 testing tree (based on 3.9-rc6) 
as we have tablets with eKTF2127 controllers and noticed a few problems.

1) __devxxxx attributes cause unused function warnings because they are 
deprecated.

2) elants_get_power_state() is only called from elants_resume() which is 
contained within a #ifdef CONFIG_PM_SLEEP. You should also move the 
elants_get_power_state() inside the #ifdef to remove the unused_function 
warning when compiled without CONFIG_PM.

Regards
Tony Prisk
