 fix kernel 2.6.27-rc7

Dear Greg and Alan,

Well, OK, but I will change it as follows:
 
  result = usb_stor_control_msg(us, us->send_ctrl_pipe,
           USB_REQ_SET_FEATURE,
           USB_TYPE_STANDARD | USB_RECIP_DEVICE,
           0x01, 0x0, NULL, 0x0, 1000);

Because the parameters of  USB_REQ_SET_FEATURE, USB_TYPE_STANDARD and USB_RECIP_DEVICE are all Hex, so I want to keep my other parameters to be consistant with them.
And I see the same using with me in the kernel. Such as the code of the  function usb_stor_euscsi_init in initializers.c file.

Is this changing can be accepted by you? 

If so, I will resubmit the new patch as soon as possible.

Hope for your reply soon.

Thanks.

The original codes are:
us->iobuf[0] = 0x1;
  result = usb_stor_control_msg(us, us->send_ctrl_pipe,
           USB_REQ_SET_FEATURE,
           USB_TYPE_STANDARD | USB_RECIP_DEVICE,
         0x01, 0x0, us->iobuf, 0x1, 1000);

Best Regards,

Franko Fang
