* mei: Simplify the ME client enumeration codeSamuel Ortiz2012-11-214-86/+95
| | | | | | | | | | | After enumerating all ME clients we call the client init functions for all matching UUIDs from a separate context. This remove the hackish cascading client initialisation process that was interleaving properties and connection command replies.

* mei: use structured buffer for extra write bufferTomas Winkler2012-11-213-27/+22
| | | | | | | | | | The structure of the message is static so we don't have to use and cast the buffer. We can also drop extra_write_index variable as this information can be extracted directly from the message header Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
