Demand for hid_input.c's process

Dear Sir or Madam

I'm facing a problem because of the implementation in "hid_input.c".
The function, “hidinput_configure_usage()” handles many usage.
However, usage=0x45(Eraser) is not supported on usage-page “HID_UP_DIGITIZER”.
So, this function add key “BTN_MISC” to map (because unknown usage) then.
I’d like to add the key which is endemic to eraser like “BTN_ERASER”.
Could you please add the process to “hidinput_configure_usage()”?
Or, if you can’t, could you please permit me to fix the process?

Thank you,
Best Regards,
Takeuchi.

The event code for the eraser is BTN_TOOL_RUBBER:

#define BTN_TOOL_PEN            0x140
#define BTN_TOOL_RUBBER         0x141
#define BTN_TOOL_BRUSH          0x142
#define BTN_TOOL_PENCIL         0x143
#define BTN_TOOL_AIRBRUSH       0x144
#define BTN_TOOL_FINGER         0x145
#define BTN_TOOL_MOUSE          0x146
#define BTN_TOOL_LENS           0x147

Could you please add the process to “hidinput_configure_usage()”?
Or, if you can’t, could you please permit me to fix the process?

Please send a patch with proposed changes.

Thanks.
