[patch v3 0/3] Support of Perixx Peripad 701 for hid-multitouch

Hi Guys,

This is the v3 of the support of Perixx Peripad 701.

I included the changes asked by Henrik & Dmitry:
-           code = ((usage->hid - 1) & HID_USAGE) + BTN_MOUSE;
+           code =  BTN_MOUSE + ((usage->hid - 1) & HID_USAGE);
use of min;
remove remove the call to input_mt_report_finger_count;
remove debug information;
some cosmetic changes (parenthesis, typos)

Cheers,
Benjamin
