mei: replace check for connection instead of transitioning

2015-04-03T14:18:56+00:00

The function mei_cl_is_transitioning is just opposite
of mei_cl_is_connected. What we actually wanted to
check is if we lost connection so we can discard
the check for transition and check for 'not connected'

mei: fix regression on NFC connection

2015-03-25T10:36:37+00:00

In mei_host_client_init function we enable the all internal
connected clients including NFC. This is done before we set the device
to enabled state and let userspace call open.
We need to check only for MEI_FILE_CONNECTED in mei_cl_is_connected
in order to enable the communication with the clients before
MEI_DEV_ENABLED is set.

mei: always initialize the callback with the intended operation type

2015-03-02T03:37:00+00:00

We set the operation type at initialization time as each cb is used only
for a single type of operation

As a byproduct we add a convenient wrapper for allocating cb with
the data buffer.

mei: use only one buffer in callback

2015-03-02T03:37:00+00:00

The callback structure is used exclusively for reading or writing
therefore there is no reason to hold both response and request buffers
in the callback structure
