mei: revamp open handler counts
Make open counter to be incremented and decremented from mei_cl_link and mei_cl_unlik function respectively Nfc was assuming symmetric linking API and thus open handler count was never decreased. This patch fixes that. We need to add separate open hander count for amthif which is handled out of link/unlink functions and doesn't break the symmetric API. Last we do not waste clients slots if amthif or wd are not present in the device. we don't need to allocates slots ahead it is all covered by link/unlink before the devices is responding to user space connection and thus not racing on allocation Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
