Subject: [BUG 5/5] [BUG] media: atomisp: atomisp causes touchscreen to stop working on Microsoft Surface 3

Touchscreen input works fine before loading atomisp driver on Surface 3.

However, after loading atomisp driver, touchscreen works only when
capturing images. This sounds like atomisp turns off something needed
for touchscreen when atomisp is idle.

There is no useful kernel log. Just the touchscreen stops working
with no log.

I'll update if I find something further. First of all, can someone
reproduce this issue on the other devices?
