[PATCH] xpad - Set buffer length for outgoing requests

["Michael Gruber" <lists.mg@googlemail.com>]

From: Michael Gruber <lists.mg@googlemail.com>

The messages for led/rumble are exactly 3 and 8 bytes respectively.
Hence set up the transfer_buffer_length accordingly.

Hi, my Xbox360 Controller will not work at all unless this is set up correctly.
I am new to linux kernel programming and would appreciate any kinds of comments.
