    HID: wacom: implement generic HID handling for pen generic devices · 7704ac93
    Benjamin Tissoires authored
    ISDv4 and v5 are plain HID devices. We can directly implement a generic
    HID parsing/handling and remove the need to manually add those PID in
    the list of supported devices.
    
    This patch implements the pen support only. The finger part will come in
    a later patch.
    
    To be properly notified of an .event() and a .report(), we need to force
    hid-core to go through the HID parsing. By default, wacom.ko binds only
    hidraw, so the hid parsing is not done by hid-core. When a true HID device
    is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will
    force hid-core to parse the incoming reports.
    (Note that this can be easily backported by directly setting the .claimed
    flag to HID_CLAIMED_DRIVER even if hid-core does not support
    HID_CONNECT_DRIVER)
