Hi Ritesh,
Thank you for reporting libwacom bugs and attaching your solution to it. This project needs people like you to keep it strong.
I saw a similar patch submitted by Sjoerd on March 25:
[Linuxwacom-devel] libwacom not recognizing touch(screen) devices
Both patches make sense to me. Joaquim Rocha, who is cc'd in this email, will be responsible for libwacom project. He has the final say about your patches ;-).
Joaquim, welcome on board! Please subscribe to linuxwacom project if you have not done so. We can also grant you write access to git repository if you are ready to chime in...

this patch is unfortunately incorrect, we can't have libwacom try to detect touchscreens for the risk of false positives. Besides, touchscreens usually work different to tablets and don't usually get handled by the wacom driver these days.
This is a bug that needs to be fixed in GNOME and in a generic manner since it's not just the x220 that is affected but any touchscreen device.
