Changelogs (since 0.4.0):
1. Make hidinput_disconnect_core() be more robust, it can not break anything even failed to allocate device struct.
2. Thanks new input device driver API, we need not the extra code for support force-feed device yet, so say bye to CONFIG_HID_SIMPLE_FF.
This is one patch of The HID Simple Driver patches, for convenience, you can find them all in that mail:
[PATCH] usb/hid: The HID Simple Driver Patches 0.4.1 (all-in-one)
The code base is 2.6.19.
Is this ready to merge? or What still is problem in them? Thanks.
