Subject: [PATCH] HID: hid-multitouch: add support for SiS panel in LG 23ET83V

--------------------
From: Emanuel Krenz <emanuelkrenz@....de>

Add support for SiS multitouch panel in the touch monitor LG 23ET83V.

---

I bought an LG 23ET83V multitouch monitor, whose idProduct=1030 wasn't 
yet included in the hid-multitouch driver.
So I wrote following patch to include the ID number 1030 and patched the 
latest stable 3.12.5 kernel. The SiS touchpanel in my monitor works for 
me now.
This is my first submitted patch by now, hope it's okay.
