Dan Carpenter eccbf04a90 Staging: bcm: use get_user() to access user pointers 
This fixes some places that dereference user pointers directly instead
of using get_user().

Please especially check my changes to IOCTL_BCM_GET_CURRENT_STATUS.  The
original code modified the struct which "arg" was pointing to.  I think
this was a bug in the original code and that we only wanted to write to
the OutputBuffer. Also with the original code you could read as much
memory as you wanted so I had to put a cap on OutputLength.  The only
value of OutputLength that makes sense is sizeof(LINK_STATE) so now if
OutputLength is not sizeof(LINK_STATE) it returns -EINVAL.
