HID: waltop: fix Media Tablet 10.6 inch zooming
Browse files Browse the repository at this point in the history 
Fix zoom controls of older version of Waltop Media Tablet 10.6 inch, aka
Genius G-Pen M609. This should make it supported on par with the newer
version, aka Genius G-Pen M609X.

The fix is extrapolated from the behavior of the newer version (Genius G-Pen
M609X) and both older and newer versions of Media Tablet 14.1 inch (Genius
G-Pen M712/M712X) and should work with high probability.
