2013-01-09mei: normalize me host client linking routinesTomas Winkler1-5/+5
In order we can use the same code pattern for in-kernel and user space host clients we replace mei_cl_link_to_me with mei_cl_link function. We then have to keep me client lookupout of the new link function. The unlinking cannot be yet symetric due to amthif connection handling Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
