mei: drop unreachable code in mei_start

2017-06-13T13:46:18+00:00

Device disabled state is caught inside the retry loop, so
there is no need to check it once again afterwards.

mei: validate the message header only in first fragment.

2017-06-13T13:46:18+00:00

RX message header is received in the first fragment of
the message and saved side and it is not modified after that,
we don't need to validate it upon each fragment.

mei: make sysfs modalias format similar as uevent modalias

2017-06-03T10:10:22+00:00

modprobe is not able to resolve sysfs modalias for mei devices.

commit b26864cad1c9 ("mei: bus: add client protocol
version to the device alias"), however sysfs modalias
is still in formmat mei:S:uuid:*.

This patch equates format of uevent and sysfs modalias so that modprobe
is able to resolve the aliases.

mei: make mei_cl_bus_rescan static

2017-05-25T16:24:03+00:00

mei_cl_bus_rescan is used only in bus.c,
so make it local to the file and mark static.

mei: implement fsync

2017-04-08T15:38:25+00:00

When write() returns successfully, it is only assumed that a message
was successfully queued. Add fsync syscall implementation to help
user-space ensure that all data is written.

mei: bus: elminate variable length arrays

2017-04-08T15:38:25+00:00

Though VLA are supported by CC99 there are many cavities
and should be avoided.

'const size_t len = sizeof()' that we used may not be set
at the compile time hence generating VLA code.

This fixes also sparse warning
warning: Variable length array is used type.

mei: drop amthif internal client

2017-04-08T15:38:25+00:00

AMTHIF has special support in the mei drive, it handles multiplexing
multiple user space connection above single me client connection.
Since there is no additional addressing information there is a strict
requirement on the traffic order on each connection and on the "read
after write" order within the connection. This creates a lot of
complexity mostly because the other client types do not necessarily fall
under the same restriction.    After carefully studying the use of the
AMTHIF client, we came to conclusion that the multiplexing is not really
utilized by any application and we may safely remove that support and
significantly simplify the driver.
