In order to transmit data, the driver enables Tx and sleeps until *board_write is set to 1 by the interrupt handler. It can happen, though, that the data is sent even before the process is asleep. In this case *board_write must be set to 1 anyway, otherwise we will be waiting for a condition that will never be true. Signed-off-by:

On systems where wd and amthif is not initialized we will hit cl->dev == NULL. This condition is okay so we don't need to be laud about it.

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:
