Subject: [PATCH v2 5/5] HID: google: modify HID device groups of eel

From: Zhengqiao Xia <xiazhengqiao@...qin.corp-partner.google.com>

If HID_GROUP of eel is set to HID_GROUP_GENERIC, Whiskers Tablet Mode
Switch of eel hammer will not be detected by system because the
hid-vivaldi driver probes the device. When it is set to
HID_GROUP_VIVALDI, system will detect Whiskers Tablet Mode Switch
successfully and also support the vivaldi keyboard layout.
