This patch changes return type of wilc_get_mac_address from s32 to int.
The result variable gets return value from wilc_mq_send that has return
type of int. It should be changed return type of this function as well
as data type of result variable.

The data type of variable i changes u32 to int.
It is used as array index to copy some data with memcpy function
so that it is better to use data type of int.

Make them void __user * instead of char * (or char __user *),
void * removes the necessity of explicit casts to proper type
where people also need to remember __user qualifiers, so I think
it works better here.

In lustre/obdecho/echo_client.c, remove handling of lov_stripe_md
passed from userspace (since userspace never passes it). Remove the
LOV specific code (ed_next_islov) from the echo client (since it
doesn't work).
Remove echo_get_stripe_off_id() and all calls to it since the stripe
count of the passed in lsm is always 0 and the funciton does nothing
in this case. Remove the then unused lsm parameters of
echo_client_page_debug_setup() and echo_client_page_debug_check().
In the OBD_IOC_GETATTR and OBD_IOC_SETATTR cases of
echo_client_iocontrol() do not set the oi_md member of struct obd_info
since only LOV OBD methods access it.
