Remove comments with broken links to tablet descriptions from hid-kye/uclogic/waltop drivers. They pointed to now dead DIGImend project wiki at sf.net. Even though the DIGImend project still hosts descriptions, now at digimend.github.io, it's better to avoid them going stale again, and let anyone interested search the web instead.

* There exists an official driver on the manufacturer's website, which

|
* wasn't submitted to the kernel, for some reason. The official driver
|
|
* doesn't seem to support extra features of some tablets, like wheels.
|
|
*
|
|
* It shows that the feature report ID 2 could be used to control any waltop
|
|
* tablet input mode, switching it between "default", "tablet" and "ink".
|
|
*
|
|
* This driver only uses "default" mode for all the supported tablets. This
|
|
* mode tries to be HID-compatible (not very successfully), but cripples the
|
|
* resolution of some tablets.
|
|
*
|
|
* The "tablet" mode uses some proprietary, yet decipherable protocol, which
|
|
* represents the correct resolution, but is possibly HID-incompatible (i.e.
|
|
* indescribable by a report descriptor).
|
|
*
|
|
* The purpose of the "ink" mode is unknown.
|
|
*
|
|
* The feature reports needed for switching to each mode are these:
|
|
*
|
|
* 02 16 00 default
|
|
* 02 16 01 tablet
|
|
* 02 16 02 ink
