Re: [PATCH v2] Input: Fix the HID usage of DPAD input event generation.

[Chris Ye]

Hi Benjamin,

   We are using hid driver to inject hid report for D-Pad and Hat 
switch events, like:

      [0x00, 0x00, 0x00, 0x00, 0x01, 0x80, 0x00, 0x00, 0x00, 0x00, 
0x00, 0x00],

Check the HID format dump from kernel, this will send a 0x1 on HID usage 
GenericDesktop.HatSwitch.

Do you need me to help write the gamevice tests? I've not observed any 
regression from my side, as this patch is very specific to usage 
D-PadUp/Down/Left/Right.


Thanks!

Chris
