2013-01-08mei: reenable mei_hcsr_set abstractionTomas Winkler
Now when mei_hcsr_set is local to hw-me.c we can benefit form the fact that it wraps H_IS removal from the host csr. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-08mei: abstract host and device readienessTomas Winkler

2013-01-08mei: don't use cached value for hcsr in mei_hw_resetTomas Winkler
Open code mei_hw_reset to avoid using cached hcsr. Using cached hcsr can cause unwanted side effects. Move mei_hw_restet function to hw-me.c as it is hw dependent Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-01-08mei: normalize me host client linking routinesTomas Winkler
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.
