The amthif FW client can appear after the end of client enumeration.
Amthif host client initialization is done now at FW client discovery
time.

mei: hbm: send immediate reply flag in enum request

2016-02-07T22:47:20+00:00

Signal the FW that it can send an HBM enumeration answer immediately,
without waiting for FW initialization completion, meaning before
all the FW clients are ready and registered.

Organize enumeration response options to enum as a byproduct.

mei: bus: run rescan on me_clients list change

2016-02-07T22:47:20+00:00

Since clients can be now added and removed during runtime
we need to run bus rescan whenever me_clients list is modified.

mei: drop reserved host client ids

2016-02-07T22:47:20+00:00

The reserved host clients can be obsoleted now, a portion of the
platforms is shipped without iAMT enabled, where the reservation is not
relevant and for platforms with iAMT dynamic allocation is sufficient.
Dropping reserved ids makes enumeration more flexible and generic

mei: bus: fix notification event delivery

2016-02-07T22:47:20+00:00

Call wake_up cl->ev_wait only in case there is no bus client registered
to the event notification.
Second, since we don't have exclusive waiter wake_up_interruptible_all
is not used correctly here.

mei: bus: fix RX event scheduling

2016-02-07T22:47:20+00:00

In this particular case this more correct and safer to check if the RX
event is set in the event mask rather than query waitqueue_active
Since the check is already performed in the mei_cl_bus_rx_event
function,  it is just required to check for its return value.
Second, since we don't have exclusive waiter wake_up_interruptible_all
is not used correctly here.

mei: amthif: replace amthif_rd_complete_list with rd_completed

2016-02-07T22:47:20+00:00

Now when we have per client rd_completed list we can remove
the amthif specific amthif_rd_complete_list.
In addition in the function mei_amthif_read do not loop over the
rd_completed list like the original code as the code path is unlocked.

mei: rename variable names 'file_object' to fp

2016-02-07T22:47:20+00:00

The driver uses three names file, fp, and file_object for
struct file type. To improve code clarity and adjust to my taste
rename file_object to more common and shorter fp.

mei: constify struct file pointer

2016-02-07T22:47:20+00:00

The struct file file pointer is used as an opaque handle to for a
connected client, for this part the pointer should be immutable and
should be set to count.
